Built for full-switching power factor correction in 3-6 kW-power range motor drive applications, these devices include two fast-recovery diodes, two freewheeling diodes, two IGBTs, a gate-driver IC, a shunt resistor and a thermistor, all in a 44 x 26.8 mm package, using half the board space of other modules. They offer 99 percent power factor for the mandatory PFC standard, plus 40 kHz switching operation. They offer under-voltage and over-current protection with a built-in gate-driving IC. They have an isolation voltage rating of 2500 Vrms/min. They use the company's own Direct Bonded Copper-based transfer-molded packaging technology for better thermal efficiency.
