Abstract

PURPOSE:To avoid a possibility of deterioration or destruction of a transistor by shutting off a through current completely through causing a bridge driver circuit to have a dead time. CONSTITUTION:Input terminals 9 and 8 of a comparator 10 are supplied with a reference standard signal and an input pulse signal, respectively. The output signal of said comparator 10 is given at the time of its rising and falling a certain inclination by the capacitor C and is supplied as a trapezoidal waved signal to the non-inverting input terminal of a comparator 12 and to the inverting input terminal of a comparator 13. Transistors Q5, Q8 and Q6, Q7 are controlled by outputs of the comparators 12 and 13, respectively. Thus, the use of a trapezoidal waved signal can cause the operation of transistors Q5-Q8 to have a dead time.
