Power Drive Inverter

There are many ways to classify inverters. For example, according to the number of phases of the AC voltage output by the inverter, it can be divided into single-phase inverters and three-phase inverters; according to the type of semiconductor device used by the inverter, it can be Divided into transistor inverters, thyristor inverters and turn-off thyristor inverters. 

According to the different principle of the inverter circuit, it can be divided into self-excited oscillation inverter, step wave superposition inverter and pulse width modulation inverter. 

According to the application in grid-connected system or off-grid system, it can be divided into grid-connected inverter and off-grid inverter. In order to facilitate optoelectronic users to choose inverters, this section is only classified according to the application occasions of inverters.

In the photovoltaic system, the electric energy generated by the solar cell is stored by the battery, and then converted into 220V or 380V alternating current through the inverter. 

However, the battery is affected by its own charging and discharging, and its output voltage varies widely. 

For example, the nominal 12V battery has a voltage value that can vary from 10.8 to 14.4V (exceeding this range may cause damage to the battery) . 

For a qualified inverter, when the input terminal voltage changes within this range, the change in its steady-state output voltage should not exceed ±5% of the rated value, and when the load changes suddenly, its output voltage deviation should not exceed ±10% of rated value

For loads that include motors, such as washing machines, refrigerators, etc., because the motor's best frequency operating point is 50Hz, too high or too low a frequency will cause the equipment to heat up and reduce the operating efficiency and service life of the system. 

The output frequency should be a relatively stable value, usually 50Hz, the deviation should be within ±l% under normal working conditions
