Abstract

PURPOSE:To obtain an output having highly approximate sinusoidal wave by turning a switching element ON and OFF consecutively by a pattern signal generated correspondingly to a desired output voltage waveform and a circuit for dividing the pattern signal into three phases. CONSTITUTION:A pattern generator having an ROM2 for storing several types of patterns with divided addresses, a flip-flop FF3, a data selector 4 and exclusive-OR gates 5, 6 is provided. The pattern output is inputted to signal converters 18A-18C for dividing it into three phases. The signal converter 18A converts a signal from a point Aa through an AND gate 7 into a signal a3. The signal a1 passed through an inversion amplifier 9 from the point a and the signal Aa are applied to an AND gate 8, and converted into a signal a4. The inverted signal a2 from the point a and the signal a3 (a4) are applied to an OR gate, which in turn produces a signal a5 (a6). The signals a3-a6 are shaped through a delay circuit 11 to signals a3'-a6' respectively. The combinations of the signals a3 and a6', a5 and a4', a6 and a3' are respectively inputted to NAND gates 12-15 of next stage, and signals Ta1-Ta4 are produced as logic product outputs. The converters 18B and 18C are similarly processed.
