Abstract
PURPOSE:To prevent switching distortion by keeping all the transistors at ON state regardless of the polarity of input signal, by connecting the series circuit of a resistor and a capacitor between the common junctions with two sets of resistor and diode. CONSTITUTION:The series circuit of a resistor 13 and a capacitor 12 is connected between the common points of the resistor 3 and the diode 4, and the resistor 9 and the diode 10. Further, when the input signal of positive half cycle is input, the emitter current of transistors TR1, 2 is increased and power is fed to the load 6, but TR7 keeps ON-state. This is the same when the input signal of negative half cycle is fed. In this case, since forward voltage should be fed to the diodes 4, 10 at all times, the resistance value of the resistors 3, 9 is selected so that forward voltage is always fed to the diodes 4 and 10. Accordingly, TR1, 2, 7, 8 are always at ON state, resulting in preventing switching distortion.
