A transformer has a primary winding and a secondary winding. A center tap of the primary winding is connected with one end of a d.c. power supply. Both ends of the primary winding are connected to the drains of transistors (Q1) and (Q2) that constitute switching elements, respectively. Also, the sources of the transistors (Q1) and (Q2) are connected to the other ends of the d.c. power supply. The gates of the transistors (Q1) and (Q2) are connected to one ends of gate resistors (R1) and (R2), respectively. The other ends of the gate resistors (R1) and (R2) are connected to a control circuit, and the resistance of the gate resistor (R2) is larger than the resistance of the gate resistor (R1).
