Introduces the working principle of the inverter

Transformer is a kind of DC to AC transformer, it in fact and converter is a process of voltage 6000 watt power inverters. The converter is the transformation of the city power grid AC voltage is 12V DC 4000 watt power inverter, and the 12V output DC voltage Adapter into high-voltage alternating current frequency; two parts are also using a pulse width modulation more with the current (PWM) technique

Research on the problem of SPWM inverter

Three phase bridge AC power inverters circuit, the earth with bipolar SPWM modulation technology. Any power switch solid tube are there exists a turn-on and turn off time, to ensure not to attack through the wrong switch tube unified bridge under the arm, the earth the fantasy SPWM drive signal rising edge Off grid inverter(or falling) off a period of time (called Td dead time). The dead zone is accepted in order to guarantee the safe and reliable operation of switching devicesway.




Power Inverters

Power inverters produce one of three types of power wave signals. Each signal represents a quality of power output. The first set of 2000 watt power inverter made which are now obsolete produced a Square Wave signal. Square Wave signals produced power that was not reliable or consistent

power inverter

Inverter, an 24 volt power inverters device must be something to so called, he and transformer has a direct difference, that is to say, he can realize the input and output DC, AC, working principle and switch power source, but the shock frequency in a certain range, for example if the frequency is 50HZ, the output is for the exchange of 50HZ. The 220 volt power inverters is can change its frequency equipment.
