Title: Ac/dc inverter control system
Inventor: TSUTSUMI TAKESHI
IPC: H02M7/48
Filed: 1991-11-22
Abstract: PURPOSE:To simplify the circuit constitution and cut down the device scale by inverting the pulse width of a positive pole thereby generating the pulse width signal of a negative pole, in the control system of an inverter device which converts DC power into singlephase AC power. CONSTITUTION:A DC/AC inverter (0) A converts DC power E into cycles a half time as long as the positive pole of sine wave AC power, and a DC/AC inverter (1) converts it into cycles a half time as long as the negative pole. An error amplifier C compares output voltage with the reference voltage of a sine wave reference voltage part D, and outputs an error signal, and a PWM circuit part E converts it into a pulse width signal. To extract control information by this signal and distribute it to two systems of DC/AC inverters A and B, signal processing is performed in a wave making circuit part A. This wave making circuit part F uses a pulse width signal as it is, when generating the sine wave AC voltage of a positive pole, and converts a pulse width signal and uses it when generating the sine wave AC voltage of a negative pole, and the changeover is performed by the signal of a driver changeover controller G.
