Title: Power recovery time processing system of inverter
Inventor: KAWASHIMA TETSUYUKI
IPC: H02P27/06
Filed: 1984-01-20
Abstract: PURPOSE:To eliminate the flow of an abnormal current even if a power is interrupted by decelerating the rotation of an electric machine while preventing the reverse flow of the effective power to an inverter from a motor at the power interruption time. CONSTITUTION:When the power source voltage detector 6 detects the power interruption or a voltage drop of an input power source 1, a signal generator 8 applies a negative signal to an adder 10, and also to an electromagnetic contactor 19 to open the contactor 19. In other words, the contactor 19 interrupts the circuit between the power source 1 and an inverter I so as not to regenerate the power at the power interruption time. Since the contactor 19 is opened at the power recovery time, the current from the power source 1 is flowed through an initial charger 20 to the inverter I, and a filter condenser 3 is gradually charged through a rectifier 2. Accordingly, the rush current is not flowed.
