In applications requiring the reliable operation of electric vehicle drives—such as in rail vehicle technology—specialized gate drive transformers ensure a stable power supply for the dependable operation of IGBTs and MOSFETs in full-bridge or half-bridge topologies. Traditional bootstrap circuits are not suitable for these requirements. Our PTR series offers excellent characteristics, including high isolation voltage strength, a compact design, and low coupling capacitance between the control side and the power stage. A very wide operating temperature range from –40°C to +105°C enables use across many different climatic zones. The PTRs operate with switching frequencies between 25 and 75 kHz and serve as the interface between the microcontroller control side and the IGBT power stages with ±12V or ±24V driver supply voltages. On the power electronics side, the transformed square-wave voltage is converted into a DC voltage via a bridge rectifier and capacitor to switch the IGBTs. This allows for the stable operation of various power semiconductors with high input capacitance.
