Abstract

PURPOSE:To eliminate the need of a timing generation circuit, by performing the short-circut/non-short-circuit of a rush current preventing resistor corresponding to the presence/absence of the input of an existing operation display signal. CONSTITUTION:Since no converter operation display signal is taken out until a microprocessor enters a normal operating state by applying a power source, relay switches 24a and 25a are connected to sides shown in continuous lines, thereby, resistors 10 and 11 are connected to capacitors 4 and 6 in series, and the capacitors 4 and 6 can be prevented from being damaged due to a rush current. Next, when the microprocessor enters the normal operating state, the converter operation display signal is impressed on a flip-flop 28 from the microprocessor via a terminal 27. Relay switches 26a and 6b are switched and connected to the sides shown in broken lines, which short-circuit the resistors 10 and 11, respectively.
