Abstract
PURPOSE:To improve the power factor of the operation of an inverter, by giving a coefficient which is proportional to a DC voltage to a triangular wave signal. CONSTITUTION:The output isgnal from a voltage detector 19 which is connected to the output terminal side of a DC power source 1 is introduced to a multiplier 20. The coefficient which is proportional to the change in the DC voltage is given to the triangular wave signal from a triangular wave oscillator 15, and the result is inputted to a pulse width modulator 16. In the meantime, a control signal A (sine wave signal) which specifies the width, frequency, and phase of the fundamental wave of the output voltage of the inverter is also introduced into the pulse width modulator 16. The signals A and B are switched in the pulse width modulator 16, and the modulated pulse signal is sent to the inverter 2, and a converting valve of said inverter is controlled.
