Abstract

PURPOSE:To prevent the penetration phenomenon through a simple circuit constitution by providing the diode featuring the forward connection relation between two series-connected switching elements and then applying the reverse bias to the switching element of the higher potential side. CONSTITUTION:Transistors TrQ1 and Q2 forming two switching elements are connected in series to power source Va, and the alternating switching control is given to TrQ1 and Q2. Thus resistance R2 is connected to diode D featuring the forward connection between TrQ1 and Q2 connected in series for the circuit which applies the alternating voltage to the load from the serial connection point of TrQ1 and Q2. At the same time, the connection point of one end of diode D and TrQ2 of the lower potential side is connected to the gate electrode of TrQ1 of the higher potential side, and the capacity load is connected to the connection point between the emitter of TrQ1 and the other end of diode D. Then the reverse bias is applied to TrQ1 of the higher potential side to prevent the penetration phenomenon.
