Abstract
A control unit (4) generates a control signal. A switching device (2) performs switching according to the control signal and generates a primary side input voltage from a supply voltage. A transformer (1) converts the primary side input voltage to a secondary side output voltage. A drive circuit (7) drives a power device (8) according to the secondary side output voltage. The control unit (4) includes a table listing a correspondence relationship between supply voltages and set values of control signals for obtaining a desired secondary side output voltage, refers to the table and generates the control signal having a set value corresponding to the supply voltage.
