Title: Biased magnetism preventing circuit of output transformer of three-phase inverter
Inventor: SUGIMOTO TAKASHI
IPC: H02M7/48
Filed: 1991-10-07
Abstract: PURPOSE:To prevent at a biased magnetism and the saturation of an output transformer by installing an adder which changes a zero potential of a modulated signal generater due to the output of a dc component detector. CONSTITUTION:The output current of each phase of a three-phase switching circuit 3 which is detected by an output current detector 11a is a sine wave ac containing a ripple of a frequency of a chopping wave Er as a carrier signal. Therefore, if a cut-off frequency of a low-path filter 11b is made very much smaller than the frequency of that sine wave, the dc voltage proportional to a dc component of the output current can be output from the low-path filter 11b. An adder 12 inverses the dc voltage from a dc component detector 11 and adds it up to the output of a modulated signal generator 8 to change a zero potential of a modulated signal. Therefore, such a PWM signal can be obtained as to remove a dc component of the output current of each phase of the three-phase switching circuit 3. By this method, a dc component can be removed from the output current of each phase of the three-phase switching circuit 3.
