Abstract
PURPOSE: To reduce chattering by detecting voltage drop across capacitor arranged in parallel with a D.C. power source and triggering a timer then stopping an inverter based on a time elapse signal.
CONSTITUTION: A solar generating system comprises solar cells 1, a commercial power system 2 and an inverter 3. An A.C. switch 6 for regulating the phase of output current from the inverter 3 and feeding the output current to the commercial power system 2 is provided. A controller therefor comprises a sequence control circuit 7, an inverter drive circuit 8, a D.C. voltage constant control circuit 9, an error amplifier 13, a pulse width control circuit 15, a zero voltage detection circuit 16, a triggerable timer 37, etc. When output voltage from the D. C. source 1 exceeds over starting voltage, that voltage is detected through the control circuit 7 and starting of the inverter 3 is controlled. When the output voltage from the D.C. source 1 drops below a referential level, the timer 17 is triggered and if it is not reset within a setting time, the inverter 3 is stopped through the control circuit 7.
