Title: Voltage controller of permanent magnet generator
Inventor: TAKEUCHI KIYOSHI
IPC: H02P9/04
Filed: 1996-05-29
Abstract: PROBLEM TO BE SOLVED: To reduce the number of large current switching devices, to eliminate a large current control circuit, and to realize the size reduction and the weight reduction, by a method in which an AC converting means is composed of an equi-width PWM control circuit having a voltage regulating function. SOLUTION: Transistors T2-T5 of an inverter circuit 7 are controlled by an equi-width PWM control type inverter circuit 8. If a DC voltage is higher than a target voltage, an output voltage is turned on and off the lower the voltage. The ON-period and the OFF-period are determined by a differential voltage between the DC voltage and the target voltage and are set so as to make a 3-phase AC voltage constant. If the DC voltage is lower than the target voltage, the PWM control is not carried out. With this constitution, the number of large current switching devices can be reduced, so that the size reduction and the weight reduction can be realized.

Filed: 1987-06-26
Abstract: PURPOSE:To obtain a multiple inverter device of a higher harmonic current or reactive current control type which does not need two serial transformers, by using a 2nd constant voltage control circuit to control simultaneously the voltage of two DC capacitors. CONSTITUTION:The charging current is decided by a 1st constant voltage control circuit 5 with the voltage ED1 of a 1st DC capacitor 3-1 defined as the feedback value so that the 1st DC voltage is constant. This decided charging current is used to charge 1st and 2nd DC capacitors 3-1 and 3-2 of a PWM converter. At the same time, the voltage ED2 of the capacitor 3-2 is defined as the feedback value to add the output DELTAEC obtained from a 2nd constant voltage control circuit 9 to the output voltage EC of a 1st single phase PWM converter which is decided by a 1st constant current circuit 7. Thus the compensation is ensured so that the output voltage of a 2nd single phase PWM converter is equal to (EC+DELTAEC). As a result, the voltage of both DC capacitors are controlled at one time. Then the fixed current control is possible for the DC capacitors and a multiple PWM inverter device of a higher harmonic current or reactive current control type is obtained.
