Abstract :
The scheme of full-decoupling in circuit and magnetic circuit is proposed, in terms of the conventional inverter not matching any unbalanced loads. Voltage independence control and closed-loop control can be done by PLL, respectively in each phase, to let the output phase track the references, which ensures the inverter phase to symmetry. This paper discuss the method of phase feedback control mainly. Experiment results of 12 kW three phase inverter show that the circuit design is feasible. It is suit of high power inverter.
