Abstract

PURPOSE:To simplify circuit constitution by employing the first output terminal to obtain analog signal that corresponds to digital functional wave signal and a digital-analog converter that has a second terminal to output inverted signal. CONSTITUTION:When two unit inverters are multi-connected and its striking phase is controlled, the signal of a reference signal generating device 1 is given to a digital functional wave generating device 2 and it is connected to a D/A converter 4a through an N-bit bus A. From a converter 4a analog signal output Io that corresponds to the digital functional wave signal and its reversed signal output I'o are obtained from a converter 4a, and they are respectively given to comparators 6a and 6b to be compared with a control signal Vc, and the outputted of the comparison is given to pulse distribution circuits 7a and 7b to control each of unit inverters. Accordingly only one D/A converter is used and the circuit construction and adjustment can be simplified in a great deal.
