The constant power load (CPL) property of load converter with tight control can cause instability in the DC bus voltage of cascaded power converters system. To solve this problem, an idea by combining virtual resistor (VR) based active damping control (ADC) method for load converter with hardware DC bus voltage conditioner (DBVC) is proposed in this paper. By establishing common compensation index and proper design, the DC bus voltage can be stabilized with reduced DC bus capacitor, the impact from DC bus voltage fluctuation to the load converter output voltage can be reduced by comparing to the case with ADC method only, and because the VR method shares part of the compensation function, the power volume of DBVC can be decreased accordingly, this might result in higher power density and lower power loss potentially compared to the case with DBVC only. Simulation results are provided to demonstrate the validity of the proposed method.
