Abstract

PURPOSE:To obtain a controlling device having flexibility with a simple structure by inputting the content of a memory cell by a set operation frequency value and a set voltage value into a microprocessor, and calculating them to obtain a PWM waveform. CONSTITUTION:A reference oscillation frequency is generated from a reference oscillator 11, and a set operation frequency value set by other setting circuit 8 and a set voltage value are read by a microprocessor 9. The number of clocks determined by the operation frequency is read by a memory cell 10, the prescribed calculation is achieved, and the calculated result is stored in a memory cell 13. The output of the microprocessor 9 is fed from an output port 14 to a gate circuit 15, and a main circuit controlling element 7 is turned ON or OFF by the microprocessor 9 based on a signal to the gate circuit 15.
