Abstract: The present disclosure attempts to improve performance of a semiconductor apparatus including a power transistor such as an IGBT. In a semiconductor apparatus, an IGBT module 110 includes IGBT elements SWa and SWb connected in parallel to each other, a resistor R1a connected to a gate terminal of the IGBT element SWa, and a diode D1a connected in parallel to the resistor R1a. In the diode D1a, a direction toward the gate terminal of the IGBT element SWa is a forward direction. With this configuration, it is possible to prevent gate oscillation and to improve switching characteristics.

Abstract: A driver circuit for powering a load is disclosed. The driver circuit includes an input for receiving for connection to a source of AC power, and a rectifier for converting the AC power from the input into DC power. The driver circuit also include a voltage bus filter, a high-frequency oscillator for generating a high-frequency AC signal, a resonant driver, a feedback circuit, and a high-frequency DC rectifier. The voltage bus filter smoothens the DC power from the rectifier, and includes at least one capacitor. The resonant driver is in electrical communication with the high-frequency oscillator, and limits a current of the high-frequency AC signal and produces a limited output voltage based on the high-frequency AC signal. The feedback circuit is in electrical communication with the resonant driver and the voltage bus filter, and maintains a charge on the capacitor of the voltage bus filter.
