| Abstract: | A new type of soft switch BUCK is introduced to regulate the output power of an inverter in this paper. The drawbacks of the conventional ZCT -PWM BUCK chopper can be overcome by the proposed chopper. By adding some auxiliary switching elements, such as a resonant inductor as well as a capacitor, and compared with the hard switc- hing chopper, that the main switching element turned on in ZCS and the main diode turned off in soft state can be real- ized with the proposed one. The power system is provided with lower switching losses, simpler structure and easier controlled performance. This paper analyses the circuit principle and experiment, the experimental results show that the cost-effeetive prototype based on the proposed chopper is suceessfully operated at output up to 2.5 kW. |
