METHOD FOR CONTROLLING SOLAR LIGHT INVERTER

摘要

PROBLEM TO BE SOLVED: To improve control characteristics of a solar light inverter which drives an AC motor for driving a pump by applying a solar battery to a power source. SOLUTION: The integration time of an acceleration and deceleration adjusting apparatus 51 can be adjusted by an inverse number computing circuit 52, a gradient coefficient computing element 53 and a multiplication computing element 54 which are added to a control unit 50. An acceleration time and a deceleration time of an AC motor 3 are made longer in the vicinity of the maximum power point of a solar battery 1, and the whole response characteristics are also improved while the control operation is made smooth.
