Inverters, also known as power regulators and power conditioners, are an integral part of the photovoltaic system. The main function of photovoltaic inverters is to convert the DC power generated by solar panels into AC power used by home appliances. The power generated by solar panels must all be processed through inverters before they can be exported. Through the full-bridge circuit, the SPWM processor is generally used to modulate, filter, boost, etc., to obtain the sinusoidal alternating-current power supply system end users that match the lighting load frequency and rated voltage. With the inverter, you can use the DC battery to provide AC for the appliance.
The solar AC power generation system is composed of solar panels, charge controllers, inverters, and accumulators; solar DC power generation systems do not include inverters. The process of converting AC power into DC power is called rectification, the circuit that completes the rectification function is called rectification circuit, and the device that realizes the rectification process is called rectification equipment or rectifier. Correspondingly, the process of converting DC power into AC power is called inverter, the circuit that completes the inverter function is called inverter circuit, and the device that implements the inverter process is called inverter device or inverter.
The core of the inverter device is the inverter switching circuit, or simply the inverter circuit. The circuit completes the inversion function by turning on and off the power electronic switch. The on-off of the power electronic switching device requires a certain drive pulse. These pulses may be adjusted by changing a voltage signal. Circuits that generate and regulate pulses are often referred to as control circuits or control loops. The basic structure of the inverter device includes, in addition to the inverter circuit and the control circuit described above, a protection circuit, an output circuit, an input circuit, an output circuit, and the like.
Due to the diversity of buildings, it will inevitably lead to the diversity of solar panel installations. In order to maximize the conversion efficiency of solar energy and take into account the beautiful appearance of the building, this requires the diversification of our inverters to achieve the best way of solar energy. Conversion.
