Title:
SOLAR LIGHT OUTPUT OPTIMIZER CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2020/116559
Kind Code:
A1
Abstract:
[Problem] To provide a solar light output optimizer circuit that enables use of power generation energy without any waste even when a power generation output of a PV panel is low. [Solution] The present invention is provided with: a solar light power generation input means 200A for receiving an input of a power generation output by a solar panel 50; a switching means 300; and a voltage doubler rectifying circuit 400. The present invention has: a first power recovery circuit 110 in which a contact point between a source electrode of a second switching transistor Q2 of the switching means 300 and one end a of a primary winding of a transformer T1 of the voltage doubler rectifying circuit 400 is connected to a drain electrode of a sixth switching transistor Q6; and a second power recovery circuit 120 comprising a seventh switching transistor Q7 which has a drain electrode connected to a drain electrode of a fifth switching transistor Q5 of the switching means 300 and has a source electrode connected to a source electrode of the sixth switching transistor Q6 of the first power recovery circuit 110 and connected to an anode electrode of a third diode D3.
