Abstract

PURPOSE:To save a drive power and to improve the voltage change rate and the stability by cutting an unnecessary base drive signal by detecting an output current, and eliminating ON-ready circuits relative to the signal. CONSTITUTION:An output current is detected by a current detector 15, the detected output is applied to current comparators 13, 14, which compare it with reference currents I1, I2, respectively, and apply the outputs to AND circuits 9, 10, respectively. An input from a PWM wave generator 1 is input directly or through a NOT circuit 2 to the AND circuits 9, 10. Thus, the output of the AND circuit 9 or 10 is cut, and the functions of ON ready circuits 3, 4 are eliminated by closing switches 11, 12.
