摘要：
The Zero-Voltage Transition (ZVT) PWM Converters with Resonant Auxiliary Circuit (RAC) are gathered and analyzed by means of a common topology derived in the paper. Its operation modes are identified and analyzed. In addition to the unified analysis of the ZVT PWM converters with RAC, a theoretical comparative analysis addresses the converter current and voltage stresses. By means of this analysis the main characteristics and constraints of the converters are identified. An experimental efficiency comparison is also carried out. The experimental results have been obtained from ZVT PWM boost prototypes operating at 1 kW, 100 kHz.
