“…On this basis, the interleaved parallel based on phase shift of carrier wave can reduce the power loses by decreasing current stress while suppressing switching ripple [4, 5], but it also increases the switching frequency circulating current between paralleled legs [6]. In [7], input or output is isolated to block the circulation path, but it will result in isolated power supply requirements and make the input transformer structure more complicated, not to mention the inability to apply interleaved parallel mode to reduce input and output ripple.…”

In this study, the third harmonic injection method based on analogue circuit is applied in the interleaving parallel three-phase four-leg (3P4L) inverter, the adverse effects of injected signals on the circulating current are found, and the corresponding control strategy solution is proposed. At the beginning of this study, by using the large-signal model of leg, it is proved that four legs can be decoupled, on the basis of this conclusion, the current sharing control strategy based on dual-loop scheme and third harmonic injection can be applied in paralleled 3P4L inverter, however, peak value of circulating current is increased by zero-sequence component which is caused by injected signals. Therefore, output impedance analysis method is applied, and the control strategy including zero-sequence component feedforward loop is proposed, which can be implemented with analogue circuit, and is suitable for the 400 Hz synchronous/interleaving paralleled inverter systems. Finally, the effectiveness of the control strategy is verified by simulation and experiment.

“…A parallel topology could reduce cost and current or voltage ripple by interleaving technology [3], but increases the current flow through power switching devices, increase the loss of converter, and perhaps breakdown inverter system. In literatures [4, 5], parallel topology with isolated DC or AC bus interdict circulation path, whereas power modules need to be isolated and structure of transformer is complex, the additional electrical components will increase the system cost and improve extra weight.…”

“…In [9] a resonant controller is presented for the operation of a 400[Hz] ground power unit considering the computation delay to keep reduced THD of the output voltage. In [10] a new control strategy is introduced using resonant controllers for the operation in parallel of 400[Hz] converters in ground power units (GPUs) for aircrafts. Parallel operation is required when a single equipment cannot meet the power requirements.…”
