Abstract
The invention provides a zero-loss photovoltaic follower, which solves the problem of current inversion in the prior art and relates to the technical field of photovoltaic systems. The zero-loss photovoltaic follower comprises a solar battery and electric energy output circuits connected with the solar battery, wherein the electric energy output circuits are connected in series with control switches of which the on/off is controlled by a controller; the signal input terminal of the controller is connected with the electric energy output circuits through collection circuits and collects signals of the electric energy output circuits through current transformers; and the collection circuits are respectively connected to the electric energy output circuits at the upstream and the downstream of the control switches. The zero-loss photovoltaic follower is reasonable in design, is suitable for a solar PV system, and can solve the problem of current inversion in a conventional solar battery electric energy output circuit. Compared with the prior art, as the electric energy output circuits are connected with the controller, the current direction in the electric energy output circuits can be real-timely monitored; reverse current can be promptly blocked through the control switches to avoid energy loss; and remote control is realized.
