Title:
METHOD AND CIRCUIT FOR CONTROLLING FREQUENCY OF ELECTRONIC TYPE INVERTER
Document Type and Number:
Japanese Patent JPH04222467
Kind Code:
A
Abstract:
PURPOSE: To provide a clock signal frequency control method for output frequency control of an electronic inverter and its circuit. CONSTITUTION: According to the method of the present invention, a clock signal comprising voltage pulses of a first frequency is generated, a control signal made of voltage pulses with a frequency lower than that is generated, the frequency of voltage pulses of the control signal is increased in continuous time intervals, a clock signal and a control signal are combined together, a voltage pulse of the clock signal is omitted for each voltage pulse of the control signal, and a corrected clock signal is obtained. This corrected clock signal has a ramp-up or ramp-down frequency, depending on the first frequency of the control signal and the direction into which the frequency of the control signal is changed.
