PURPOSE: To decrease capacitor capacitance of an integrating circuit by actuating a monostable multivibrator circuit by the timing of turning off a switching element, and interrupting a signal, turning on the other switching element of constituting an arm, during this metastable time. CONSTITUTION: Capacitance of a capacitor C1-1 in a basic on/off circuit 10-1 is left less than 1. Resistors R20-R24 and comparators COM4, COM5 are set equal to the past. A monostable multivibrator 17-1 outputs a low level signal for a fixed time (several microseconds) which is a trailing edge signal, to interrupt a signal of the other switching element of an arm by a diode D50. Similarly a monostable multivibrator 17-2 outputs a low level signal, which is a trailing edge signal, for a fixed time (several microseconds), to interrupt a signal of the other switching element of the arm a diode D51. |
