An induction furnace is an electrical furnace in which the heat is applied by induction heating of metal. Induction furnace capacities range from less than one kilogram to one hundred tons, and are used to melt iron and steel, copper, aluminum, and precious metals.

An advantage of induction heating is that the heat is generated within the furnace’s charge itself rather than applied by a burning fuel or other external heat source, which can be important in applications where contamination is an issue.

Operating frequencies range from utility frequency (50 or 60 Hz) to 400 kHz or higher, usually depending on the material being melted, the capacity (volume) of the furnace and the melting speed required.

Power semiconductors have various designs. MS Power makes semiconductor devices for induction furnaces in stud and disc housings.

MS Power offers a wide range of customization options based on individual customer requirements to technical parameters, connections and appearance of devices. Please contact the sales department for more info.

Traction substations are used to convert alternating current into direct current used in electric vehicles. DC traction motors are the most common drives used in electric trains.

Avalanche-type diodes are used in railway transport since they are the most stable and reliable in overload state. Such diodes are able to withstand in avalanche breakdown condition. These diodes can carry high loads due to their ability to dissipate a power pulse for a much longer period of time.

MS Power makes power semiconductor devices for electric trains in stud and disc and housings. Also manufacture isolated base power modules.

MS Power offers a wide range of customization options based on individual customer requirements to technical parameters, connections and appearance of devices. Please contact the sales department for more info.

Welding is a fabrication process whereby two or more parts are fused together by means of heat, pressure or both forming a join as the parts cool. Welding equipment provides fast and reliable fusion of various metal parts and it is an integral part of almost all industries of manufacturing, construction, metallurgy, making metal structures, automotive, etc.

Power semiconductor devices are an integral part of all welding machines. The MS Power company produces power semiconductors for welding machines and robots.

Welding diodes produced by MS Power are used in resistance welding machines. Operation of diodes in welding machines is characterized by short-term cycles of current pulses leading to the heating of the semiconductor structure followed by its cooling. As a result, the devices are subjected to repeating cyclic thermomechanical stress. This dictates stringent requirements to the static and dynamic properties of devices.

IGBT modules manufactured by MS Power are widely used in welding inverters. This type of welding implies high frequencies. The required welding current is achieved by converting high-frequency currents.

It is also worth to mention the continuous development in sector of welding robots. These solutions, as a rule, are commonly used in heavy industry. The welded products are moved on a conveyor in front of the manipulator during the manufacturing process, and a precisely configured robot performs the welding with a high degree of accuracy. The speed and continuity of work allow to perform a large number of operations per minute, while the interface allows the operator to calibrate welds, control the movement of the axes and the torch according to a given virtual model.

Robots are used for welding small, compact parts and large massive workpieces of any shape made of metal, alloys, plastic and other materials.

Power semiconductors manufactured by MS Power meet the highest requirements for durability, quality and precision. This is especially important in the operating environment of welding equipment.

All manufacturing processes at MS Power are organized in strict accordance with the requirements of the quality management (ISO 9001).

The industrial shift towards rotating power electronics (RPE) promotes brushless flexible rotor excitation, as well as battery-less rotor instrumentation and measurement devices for electrical machines. Recently, the high-power Diode converter has been proven to be excellent for rotating applications.

Large AC generators often have a small exciter-stator, in addition to the main stator. DC is applied to the exciter stator, to varying degree, thus producing variable AC output from the main stator. The rotor has two sections. The section inside the exciter-stator is an AC generator. This AC output will be rectified, thus providing current to a field winding, rotating within the main stator. Diodes are mounted to the rotor, to provide needed rectification.

Power semiconductors have various designs. MS Power makes semiconductor devices for rotating application in stud and disc housings.

MS Power offers a wide range of customization options based on individual customer requirements to technical parameters, connections and appearance of devices. Please contact the sales department for more info

Static Var Compensator (SVC)

The purpose of the Static Var Compensator (SVC) is to regulate and support the AC voltage and to minimize the over- and undervoltage that may occur during various faults and events in the network. Some examples demonstrate the ability to improve the power quality, e.g., due to disturbing loads such as arc furnaces, wind farms, traction loads, etc. Some SVC applications demonstrate the capability of the SVC to damp power system oscillations and to increase the power transmission capabilities of the AC system.

In fact, SVC should be the natural choice where the following qualities are required or desirable:

  • Rapid dynamic response
  • Ability for frequent variations in output
  • Output smoothly adjustable

Each in its own particular way, SVC offer benefits such as:

  • Grid voltage control under normal and contingency conditions
  • Fast response reactive power following contingencies
  • Preventing/reducing risk for voltage collapses in the grid
  • Preventing over-voltages at loss of load
  • Boosting voltage during under-voltage disturbances and faults
  • Damping active power oscillations

SVC can be built using a variety of designs. However, the controllable elements used in most systems are similar. The commonly used controllable elements are:

  • Thyristor-controlled reactor (TCR)
  • Thyristor-switched capacitors (TSC)
  • Thyristor-switched reactor (TSR)

SVC configuration : TCR/TCS/Harmonic filters

As TCR produces harmonics during operation, filters are required as parts of SVC design. When the SVC is required to safeguard power quality at the point of common connection in grids feeding heavy installations such as railways, steel plants and mining complexes, additional harmonic filters usually need to be included in the SVC scheme.

Power semiconductors have various designs. MS Power makes power semiconductor devices for SVC in disc housings.

MS Power offers a wide range of customization options based on individual customer requirements to technical parameters, connections and appearance of devices. Please contact the sales department for more info.

Power Supplies

The efficient use of the planet’s energy resources depends not only on the methods of exploiting them, but also on the ways of storing the generated energy. Renewable energy technology continues to advance and grow in popularity. Also, the volume of the energy storage market is growing very fast. Electricity from renewable sources is generated in an uneven manner. For example, solar energy is mostly generated during the daytime, so it must be stored for later use.

Energy storage systems help to smooth out the difference between the peaks of power generation and periods of high grid load. Power storage systems can provide a strong boost to the efficiency of energy sources and optimize related costs. If necessary, they can even ensure complete autonomy.

Power semiconductors have been successfully used in a wide variety of solutions in this field Power supply and energy storage.

Uninterruptible power supplies (UPS) make a significant share of the energy storage industry. Such devices provide continuous power to connected equipment when the main power source becomes unavailable. The UPS also protects equipment from power surges, which is important for regions with unstable power supplies.
