What is inverter

The pure sine inverter 3000w is also called the power regulator, which can be divided into two types: independent power supply and grid connected. According to the waveform modulation method can be divided into square wave inverter, step wave inverter, pure sine inverter 3000wand combined three-phase inverter. For the inverter used in the grid connected system, it can be divided into transformer type inverter and inverter without transformer.

The pure sine wave inverter 3000w is a kind of power adjusting device which is composed of semiconductor device, mainly used to convert DC power into AC power. Generally consists of a boost circuit and an inverter bridge circuit. The boost circuit raises the DC voltage of the solar cell to the voltage required by the output of the pure sine wave inverter 3000w, and the inverter bridge circuit converts the boosted DC voltage to the common frequency AC voltage. The inverter is mainly composed of switching elements such as transistors, so that the DC input can be changed into an AC output by regularly switching on and off. Of course, this is simply by the open and closed loop inverter output waveform which is not practical. The general need to adopt sinusoidal pulse width modulation (SPWM), the voltage at both ends of the narrow width close to the sine wave become narrow, central voltage width of sine wave widen, and in the half period always let the switching element act in a direction at a certain frequency, this forms a pulse train. Then let the pulse wave form a sine wave through a simple filter.
