How to control a single phase inverter?

This control is based on the single phase inverter controlled by bipolar PWM Switching and lineal current control. The electrical scheme of the system is presented. The approach is widely explained. Simulations results of output voltage and current validate the impact of this method to determinate the appropriate control of the system.

Which operating mode should a PV inverter use?

For example, this can be operation of electrical machines in commercial and industrial plants without additional compensation equipment. In such systems, the PV inverters will generate almost only reactive power and hardly any active power. In such cases, the "open-loop control" operating mode is recommended.
