Abstract

Concerning the common-mode current problem and the magnetic saturation problem of energy storage inductor in the single-stage current-source inverter

a multi-input current-source inverter with bypass switches and multi-winding high-frequency transformers is adopted. Concerning the energy management and the loop decoupling problem of the multi-energy system

a one-cycle control and master- slave power energy management strategy based on power ratio is proposed

which aims to realize the stable operation of different power supply modes

smooth transformation of different power supply modes

and decoupling operation of the control-loop. The intensive theoretical analysis of the circuit structure

energy management control strategy

and small-signal model of the system is carried out

the control loop of the system is designed

and finally a 2.5 kVA prototype of single-stage current-source inverter with photovoltaic-wind dual-input is developed to validate the adopted circuit topology and energy management control strategy.
