Novel Zero-Current-Transition PWM Converters
نویسندگان
چکیده
A new family of zero-current-transition (ZCT) pulsewidth-modulated (PWM) converters is proposed. The new family of converters implements zero-current turn-off for power transistor(s) without increasing voltagdcurrent stresses and operates at a fixed frequency. The proposed converters are deemed most suitable for high-power applications where the minority-carrier semiconductor devices (such as IGBT’s, BJT’s, and MCT’s) are predominantly used as the power switches. Theoretical analysis is verified on a 100 kHz, 1 kW ZCT-PWM boost converter using an IGBT.

This paper presents a new family of pulsewidthmodulated (PWM) converters, featuring soft commutation of the semiconductors at zero current (ZC) in the transistors and zero voltage (ZV) in the rectifiers. Besides operating at constant frequency and with reduced commutation losses, these new converters have output characteristics similar to the hard-switchingPWM counterpart, which means that ther...

In this paper is introduced a new family of DC-DC PWM converters using a true Zero Current and Zero Voltage Transition (ZCZVT) commutation cell. The soft-switching technique utilized provides Zero Current Switching (ZCS) and Zero Voltage Switching (ZVS) simultaneously, at both turn-on and turn-off of the main switch and ZVS for the main diode. The family of ZCZVT PWM converters is obtained from...

Zero-current-transition, discontinuousconduction-mode (ZCT-DCM) converters are introduced in this paper. Compared to hard-switching (PWM) converters in DCM, the ZCT-DCM converters have similar current stresses and conduction losses, and much reduced turn-off switching losses. At the expense of increased voltage stresses, zerocurrent/zero-voltage switching is maintained for a wide range of loads...

This paper proposes a new zero-current-switching (ZCS) pulsewidth modulation (PWM) switch cell that has no additional conduction loss of the main switch. In this cell, the main switch and the auxiliary switch turn on and turn off under zero-current condition. The diodes commutate softly and the reverse-recovery problems are alleviated. The conduction loss and the current stress of the main swit...
