Vehicles with electric drives are operated, for example, using H-bridge and half-bridge IGBT and MOSFET circuits. The power semiconductors are operated at intermediate circuit voltages of 1500VDC to 3000VDCtyp. Rapid switching on and off of the transistors enables compact transformers for energy transmission and the supply of electric motors.
This requires a highly reliable power supply with galvanic isolation from the µC control system. Our PTR gate driver modules were specifically developed for this purpose. High partial discharge (PD) resistance, a wide operating temperature range from –40°C to +70°C, a compact design, and execution in vacuum-potted housings offer reliable protection against external influences such as dirt and moisture. Our PTR family is available in various versions adapted to the respective power circuits. Type tests and routine tests according to the EN 50155 railway standard are standard.
