Toshiba is aiming at 60kHz power factor correction stages with a 650V 60A reduced switching loss IGBT. “Using previous generation IGBTs, the PFC stage of air conditioners would have an operating frequency below 40kHz,” it said. The new device, GT30J65MRB, comes in a TO-3P(N) and typically dissipates 350μJ when turning off at 175°C “an improvement ...
