Title: Stationary type auxiliary power supply unit for motor vehicle
Inventor: KAWAMOTO TAKEYASU
IPC: G05F1/44
Filed: 1997-04-14
Abstract: PROBLEM TO BE SOLVED: To correct the anhysteresis of a transformer by comparing an instantaneous value of the output current of an inverter device to its effective value and, if an anhysteresis current is detected at the positive side, then the output pulse at the positive side is reduced and the output pulse at the negative side is increased thereby correcting an unbalance between the positive and the negative of the inverter device. SOLUTION: An effective value is detected by an effective value detector 16 from a U-phase current 13, V-phase current 14 and W-phase current 15 which were detected by a current detector for detecting the output current of an inverter device. From the U-phase current 13, if a result obtained by subtracting a value obtained by multiplying the effective value by an arbitrary coefficient 17 is positive, then a positive definite value 18 of the anhysteresis current of U-phase is detected; and if a result obtained by adding a U-layer current 13 to an effective value multiplied by an arbitrary coefficient 17 is negative, then a positive definite value 18 of the anhysteresis current of U-phase is detected;  if a result obtained by adding a U-layer current 13 to the effective value multiplied by an arbitrary coefficient 17 is negative, a negative value 19 of the anhysteresis current of U-phase is defined as a detected value. If a counter 22 detects a positive definite value 18 of the anhysteresis current of U-phase, then 1 is added, and 1 is subtracted if a negative value 19 of the anhysteresis current of U-phase is detected, and a count value 32 of the anhysteresis current detected of the U-layer is output.
