Synchronization of output voltage waveforms in phase synchronous inverter with LCL filter for smart grid systems

In recent years, the utility grid system is more essential for the power transmission and distribution system because it cannot produce harmful gases or no discharge waste in the environment. PWM based phase synchronous invert systems are generally utilized in the high efficiency energy supply, long...

The inverter output voltage depends on the coupling transformer, input sources and invert controllers.
