INTERLINKED SYSTEM INVERTER

摘要

PURPOSE:To provide such an interlinked system inverter that the waveform of its output current has small distortion and the hourly changing maximum output power of a solar battery can be accurately taken out. CONSTITUTION:The waveform pattern storing section 23 of a control section 18 stores the waveform patterns of 256 sine waves having different amplitudes. A signal calculating and processing section 21 detects the output of a solar battery 2 and reads out the waveform pattern of the sine wave having the amplitude corresponding to the output synchronously to a system voltage. A gate driving signal generating section 26 drives an FET bridge circuit 13 in accordance with the read-out waveform pattern and the error signal of the wavefornt of the output current of an inverter 1.
