Title:
CONTROL METHOD OF POWER CONVERTER USING SOLAR BATTERY AS POWER SUPPLY
Document Type and Number:
Japanese Patent JPS6188315
Kind Code:
A
Abstract:
PURPOSE:To attain stable transition in the operation corresponding to solar radiation by detecting a rapid solar radiation with a solar battery voltage and generating a power corresponding to the solar radiation after a reference signal or a phase control signal of a power control circuit is zeroed. CONSTITUTION:When the solar battery voltage is dropped due to rapid decrease in the solar radiation, a solar battery voltage detection circuit 42 as the 1st stage is operated, a switch 37 is opened to zero the effective power reference. Then the effective power transmitted from a power converter 3 to an AC power supply 6 is decreased rapidly to suppress the reduction in the solar battery voltage. When the solar battery voltage reaches a detection voltage of the detected voltage of the circuit 42 or over similarly, the switch 37 is closed, the effective power control is started again so as to attain the operation corresponding to the solar radiation. Moreover, when the solar battery voltage is dropped, a solar battery voltage detection circuit 41 set to a low level is activated to close a switch 36 of an error amplifier 33 of the effective power control circuit thereby zeroing instantly the power transmitted from the device 3 to a power supply 6.
