Pure sine wave inverter is an electric energy conversion device that converts direct current into alternating current. It completes the inverter task by turning on and off power semiconductor devices according to a specific law.

The following editor will introduce the working principle of pure sine wave inverter.

Switching power supply is a high-frequency electric energy conversion device, which is a kind of power supply.

The switching power supply is roughly composed of four parts: the main circuit, the control circuit, the detection circuit, and the auxiliary power supply. This time, I will introduce you to the first part: the main circuit.

Last time I introduced the main circuit to you, this time I will introduce you to the control circuit, detection circuit, and auxiliary power supply.

The full name of the PWM Solar Controller is the solar charge and discharge controller. It is an automatic control device used in the solar power generation system to control the multi-channel solar cell array to charge the battery and the battery to supply power to the solar inverter load.
