Abstract

PURPOSE:To constitute a drive circuit with simplicity and at a low cost, by comparing reference signal with rectified output and making it possible to generate pulse signal of prescribed width on the basis of the result of tis comparison. CONSTITUTION:An AC power source input is rectified by a diode 11, and this rectified output is given to switching elements 13, which are controlled by driving signals A and B sent from a control unit 18, and also to a transformer 14 to be converted to AC. On the other hand, since the control unit 18 has already started generating reference signal D, if primary rectified voltage C becomes low, the point at which input of primary rectified voltage becomes lower than input of triangular wave of the reference signal D becomes quicker, and therefore, high output pulse width of a comparator 19 becomes broader, and ON time of the switching element 13 is made longer so that the AC output voltage can be kept constant.
