| Abstract: |
| Bail charge transferring zero current switching (CT ZCS) power conversion mechanism was proposed, and its conversion principle and waveform were discussed. Also the operating process was analyzed in theory by means of state trajectory equations and charts generalized. The new topology of CT ZCS based soft switching inverter has several distinct characters:The output voltage can track transient reference voltage and output analogue voltage waveform. Output terminal can bear load shock and short circuit. Both multiple inverter N+1 redundancy parallel and balanced power control become easy. Soft switching commutation is benefit for high efficiency and large capacity. Prototype experimental results confirm the feasibility and dynamic voltage tracking characteristics of the topology and its power conversion mechanism. |
