This type of inverter uses load commutation or self-commutation in which a capacitor is connected across the load so that the overall load circuit is underdamped. This inverter produces square wave output voltage from a dc power input. Let us see the circuit diagram, working, and waveforms of a basic 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 ∅. The circulating current i ab shown in Eq.
This paper also analyses the cross-current between parallel connected inverter due to the difference in output voltage magnitudes of inverters, the phase difference of inverter output voltages and difference in DC offsets present in inverter output voltages.
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 .
