1. A driver circuit, comprising:

  • a main circuit part that includes a power semiconductor device, the main circuit supplying power to a load to be connected thereto by power conversion through switching ON and OFF the power semiconductor device;

    a driver circuit part that includes a gate driver that drives the power semiconductor device of the main circuit part and a controller that controls the gate driver, an output of the gate driver being connected to a gate of the power semiconductor device to switch ON and OFF the power semiconductor device;

    a current limiting resistor provided in series in a path connecting a low-voltage side power supply terminal of the gate driver to a source of the power semiconductor device; and

    a suppression capacitor connected between a drain of the power semiconductor device and the low-voltage side power supply terminal of the gate driver.
