| Abstract: | The instantaneous current sharing control strategy is adopted based on virtual resistance in EAST fast control power supply, which is realized in the instantaneous circulating current feedback routine. Virtual resistance greatly increases the real part of the equivalent output impedance between the parallel inverters and advances the ability to restrain the low-frequency circulating current. Simulation and experimental results indicate that the control strategy is feasible and effective. |
