1200V IGBTs minimise switching losses, says onsemi
Efficient, 1200V IGBTs that minimise conduction and switching losses are intended for use in fast switching, energy infrastructure applications such as solar inverters, uninterruptible power supplies (UPS), energy storage and EV charging power conversion.
The Trench Field Stop VII (FS7) IGBTs are used to boost input to high voltage (boost stage) as well as the inverter to provide an AC output in high switching frequency energy infrastructure applications. The low switching losses of FS7 devices enable higher switching frequencies that reduce the size of magnetic components, increasing power density and reducing system cost, explained onsemi . For high-power energy infrastructure applications, the positive temperature coefficient of FS7 devices enables easy parallel operation.
The FS7 devices include high-speed (S-series) and medium-speed (R-series) options. All devices include an optimised diode for low VF, tuned switching softness and can operate with junction temperatures (TJ) up to 175 degrees C. The S-series devices, such as the FGY75T120SWD, offer the best switching performance among currently available 1200V IGBTs in the market, claimed onsemi. Tested with currents up to seven times the rated value, the rugged IGBTs are also claimed to offer best-in-class latch-up immunity. The R-series is optimised for medium speed switching applications, such as motor control and solid state relay in which conduction losses are dominant occurs. FGY100T120RWD shows a VCESAT as low as 1.45V at 100A, an improvement of 0.4V over previous generation devices.
The FS7 devices are available in a range of package styles including TO247-3L, TO247-4L, Power TO247-3L and as bare die, giving designers flexibility and design options.
