Abstract

PURPOSE:To enable to miniaturize an insulating transformer of the driving device of the semiconductor element and to constitute the insulating transformer by print patterning when a switching element is to be driven by a method wherein a control signal is modulated with a high frequency. CONSTITUTION:A DC power source is fed to the collector of a transistor 71 through the primary winding of the insulating transformer 76. The emitter of the transistor 71 is earthed, the control signal is applied from a control signal generation circuit 9 to the base thereof through a resistor 75, and moreover the base is connected to a high frequency oscillation circuit 8 through a diode 72. When the control signal is applied, the base current of the transistor 71 is modulated by the high frequency oscillation circuit 8 through the diode 72. The insulating transformer 76 is excited by the high frequency, and electric power is transmitted to the secondary side.
