This study presents various current and power-sharing control strategies of parallel-interfaced voltage source inverters with a common AC bus. A detailed classification and analysis of wired and wireless (droop) controllers for parallel-connected voltage source inverters have been done.

What is the output voltage of a parallel inverter?

In the practical system, the output voltage of two inverters which are connected in parallel either be same in magnitude U and angular frequency w or be different voltage amplitude U and U + Δ U and angular frequency w a and w b . The inverter output voltage differs by a phase angle ∅.

Can a parallel inverter work with multiple low-power voltage source inverters?

However, to achieve Parallel operation of multiple lower-power voltage source inverters modules, the output voltage has to be strictly controlled to sustain the same amplitude, phase and frequency, otherwise large cross currents (AC and DC) can damage one or more of the parallel inverters .
