Abstract

PURPOSE:To maximize memory efficiency and reduce the cost, by arranging various data tables regardless of the pulse number of output voltage, and by setting the ratio of the product of the data values to a chopper period, to be a chopper duty. CONSTITUTION:A pulse width modulation inverter converts direct current from a DC power source 111 to the alternating current of a desired value by the inverter of a transistor to generated the output. This controlling circuit is composed of a data table ROM 204 for storing various data tables, a timer counter 205, an output register 207, a digital comparator 208, and a CPU 209. Data retained in said ROM 204 consists of a chopper period data table 201, a sine wave data table 202, and a voltage data table 203. Then, the product of each data suggested by each data table is turned into a modulated pulse width, and so the pulse width modulation can be performed in good order.
