IPC: H02M7/48
Filed: 1990-04-23
Abstract: PURPOSE:To reduce at least one of the DC component and low-frequency component of an inverter output voltage by adding at least one of DC shifted excitation correction signal and low-frequency shifted excitation correction signal to a pulse width command. CONSTITUTION:In a DC regulation circuit 51, a DC shifted excitation correction value is outputted by a setting device 51A. This output is added to a pulse width command value by an adder 53. In a power-frequency voltage regulation circuit 52, a low-frequency shifted excitation correction value is outputted by a setting device 52A. The pulse width command value or polarity signal from a sine-wave generator is inputted to a zero-cross comparator 52E, of which the output is inputted to the ON/OFF control terminal of a switch 52C via logic inverting circuit 52F and directly to the ON/OFF control terminal of a switch 52D. When the output of the switches 52C, 52D is inputted to an adder 52H, a low-frequency shifted excitation correction signal is obtained and is added to the pulse width command value by the adder 53 like a DC shifted excitation correction signal.
