摘要:

在EAST 快控电源中采用瞬时环流反馈引入虚拟电阻的均流控制策略,可大大增加并联逆变器之间等效输出阻抗的实部,有效提高对环流低频分量的抑制能力。仿真和实验结果验证了该控制策略的可行性和有效性。

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.

Key words: Fast control power supply, Inverter, Circulating current, Virtual resistance
