摘要：An energy mathematical model of dual PWM structure is established, basing on the energy relationship between the energy balance and the energy unbalance of the dual PWM converter. Aiming at the problem of unbalanced system energy caused by load mutation, a constraint condition of the DC bus voltage and the d-axis component of the network side current is proposed to ensure that the system energy can be quickly restored to the steady state. The rectifier’s voltage outer ring and the power inner ring are modified by the constraint condition to realize the fast balance between the output energy of the rectifier side and the consumed energy of the inverter side, so as to achieve the coordination control of the dual PWM structure. The experimental results show that the control system can achieve fast follow-up response, restore and maintain the steady state when the load changes under the constraint condition designed in this paper, and verify the effectiveness of the strategy.
