Proton-Electrotex announces latest IGBT modules and inverters
The first introduction is an IGBT module MIHA housing with a base width of 62mm and an increased rated insulation voltage of 9500V. There are several configuration options: half-bridge, lower and upper chopper. The wide operating range is from -55 to 125°C.

The modules are designed for switching high-power loads and are used as part of converters and drives of small and medium power electric motors.

There is also a Press-Pack IGBT module in tablet form. This has two-way cooling. The sealed module housing makes it suitable for explosive and aggressive environments. The module has a uniform pressure contact of the active elements, which improves the thermal cycle resistance, explains the company. In emergency mode, it acquires a stable short-circuited state. The module is applicable for sequential switching circuits and has an operating temperature range of -60 to 125°C

The modules are used in flexible AC transmission systems (FACTS), static synchronised compensators (StatCom), static reactive power compensators (SVC), high voltage DC power lines (HVDC), wind power plants, voltage inverters for solar panels, railway transport, marine electric drive, electric drives in mining and transport machines.

Another introduction is the single component module B0 housing has a pressure-tight design and an insulated base at voltage. The modules are designed for use in energy converters, as well as in other DC and AC circuits of various power electrical installations.

Finally, an inverter power stack (pictured) is a three-phase IGBT inverter with high energy density (9 kW/kg) and high overload capacity. It contains three half-bridge IGBT modules 1200V/400A. The enclosure is sealed to IP67 and the stack’s other features are the possibility of liquid cooling, a DC link capacitor and a gate driver with over over-current, over-temperature and under-voltage protection.

The inverter power stack directs current from a vehicle's energy storage battery to three-phase alternating current to power the engine. It is intended for road and off-road electric vehicles (EVs) and hybrid (HEV) vehicles.
