Abstract
PURPOSE: To decrease losses by switching two of four switching elements in an inverter corresponding to the polarity of the output-voltage-reference signal and switching the other two corresponding to the pulse train having pluse widths which are in proportional to the absolute value of the output-voltage-reference signal.
CONSTITUTION: A sine wave having a desired frequency and desired voltage is generated by a voltage-pattern generator 71. The absolute value of said sine wave is obtained from the absolute-wave circuit 76 and is sent out. A sawtooth-wave generator 77 generates a sawtooth wave which varies from zero to the positive direction based on the reference frequency given by a timing circuit 72. A comparator 74 compares the output of the absolute-value circuit 76 and the output of the sawtooth- wave generator 77. A comparator 78 judges the polarity of the output of the voltage- pattern generator 71. The ON signal for the switching element of an inverter is formed from the logical output from the camparators 74 and 78.
