Title:
POWER CONDITIONER IN SOLAR POWER GENERATING SYSTEM
Document Type and Number:
Japanese Patent JP3941346
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve power conversion efficiency, while suppressing voltage boost as much as possible in a voltage booster circuit and limit the input voltage from the solar battery to not to exceed the breakdown voltage of the inside components, when the solar power voltage is made high.
SOLUTION: The power conditioner controller 2 for the inverter circuit 4 makes high voltage input possible, after suppressing the input voltage from the solar battery E to lower than the voltage limit, while making the booster circuit 3 through, but makes the booster circuit 3 boost the input voltage from the solar battery E to continue the operation, when the voltage drops lower than prescribed due to drop in insolation.
