The invention discloses a photovoltaic optimizer for arbitrary waveform output. The photovoltaic optimizer comprises at least one optimizer unit, a current confluence circuit and a polarity switching circuit, wherein each optimizer unit comprises a boost circuit, a reference waveform generating circuit and a control circuit. The photovoltaic optimizer can perform maximum power point tracking on a single solar panel, and can preset a reference waveform according to different waveform requirements, so as to obtain a final required waveform. Compared with the traditional optimizer which outputs direct current, the optimizer units of the photovoltaic optimizer directly output frequency doubling semi-waves of the required waveform, and the required waveform is obtained through commutation, the disadvantage that the traditional optimizer needs to be connected with an inverter is overcome, the photovoltaic system cost is reduced, the ''potential induced attenuation'' problem of photovoltaic assemblies is effectively solved, the aging rate of the photovoltaic assemblies is slowed down, and the electric energy output of the photovoltaic system is increased.
Description
technical field [0001] The invention relates to the technical field of solar power generation, and more specifically relates to a photovoltaic optimizer with arbitrary waveform output, which can be applied to solar power generation systems. Background technique [0002] In the solar power generation system, the equipment related to the field of power electronics technology mainly includes: inverter and photovoltaic optimizer. [0003] Among them, the inverter is a device that converts the DC power generated by the solar panel into AC sinusoidal power. Inverters can be subdivided into: centralized inverters, string inverters and micro-inverters. Centralized and string inverters connect solar panels in series and then perform maximum power point tracking, thereby Invert the electric energy of the solar panel into alternating current; the micro-inverter tracks the maximum power point of each solar panel, and directly inverts the electric energy of the solar panel into alternat...
