Abstract
A control unit () generates a control signal. A switching device () performs switching according to the control signal and generates a primary side input voltage from a supply voltage. A transformer () converts the primary side input voltage to a secondary side output voltage. A drive circuit () drives a power device () according to the secondary side output voltage. The control unit () 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.
