Dc/ac Power Inverter 5000w 24v 230v 5kw

With the rapid development of power electronics technology, computer technology, and automatic control technology, PWM technology has developed rapidly. 

SPWM sine pulse width modulation method is characterized by simple principle, strong versatility, fixed switching frequency, control and adjustment Good performance, can eliminate harmonics so that the output voltage contains only fixed frequency high-order harmonic components, simple design and a series of advantages, is a relatively good waveform improvement method. 

Its appearance has played an important role in promoting the development of small and medium-sized inverters. SPWM technology has become the most widely used inverter PWM technology. 

Therefore, it is of great significance to study the basic working principles and functional characteristics of SPWM inverters.

 The working principle of the power inverter

The PWM pulse is realized by the CPU microprocessor, and the low voltage 12V is changed to a DC voltage of about 300V through a high-frequency transformer. Then the CPU outputs a 50 Hz AC drive signal to drive the power switch to work. Through the successive conduction and conversion of the power tube, an AC voltage with an average effective value of 220V in the form of a square wave is output.

The output voltage of the power inverter can stabilize the voltage through its own feedback confirmation. No-load and rated voltage change is less than 10V.
