“…A better soft switching circuit is proposed, but the converter works in discontinuous mode with duty cycle less than 50% (Yao et al, 2007). Even after analyzing with duty cycle more than 50%, the number of switching phases and switching timing is high due to increased auxiliary resonance and voltage stress to the auxiliary switch (Chen et al, 2012). The higher switching frequency may cause the higher switching losses, higher Electro-Magnetic Interference (EMI) and the lower overall efficiency.…”

An enhanced soft switching technique for an interleaved boost converter with Zero Current Switching (ZCS) and Zero Voltage Switching (ZVS) during OFF and ON conditions of the main switches, that can drive large loads operated in duty cycle greater than 0.5 is proposed in this study. In this topology, auxiliary circuit is composed of resonant tank which is used to decrease the voltage stress on the main switches and a coupling capacitor is added additionally with minimum resonance which in-turn increases the life of operation of the converter. In this model, faster switching and suitable impedance matching is achieved with reduction in auxiliary circuit reactance that has contributed much increase in the overall performance. Coupled inductor in the boosting stage helps higher current sharing between the switches. The overall ripple and Total harmonics distortions are reduced in this technique without sacrificing the performance and efficiency of the converter. A simulation module constructed using "MATLAB Simulink" illustrates the better results of the proposed converter.

“…Therefore, the switching power losses cannot be set to zero in these approaches. To address this drawback, some converters have been proposed in [19]- [24]. In these approaches, the problems mentioned above are not encountered, and the main switches can be turned on and off with soft switching techniques.…”

“…Furthermore, only an additional voltage stress occurs on the main switches in the approach in [21]. These problems can be eliminated using the approaches proposed in [22]- [24]. In [22], [23], the main switches and other devices turn on and off with soft switching techniques and without additional current or voltage stresses.…”

This study proposes a novel zero voltage transition (ZVT) pulse width modulation (PWM) DC-DC interleaved boost converter with an active snubber cell. All the semiconductor devices in the converter turn on and off with soft switching to reduce the switching power losses and improve the overall efficiency. Through the interleaved approach, the current stresses of the main devices and the ripple of the output voltage and input current are reduced. The main switches turn on with ZVT and turn off with zero voltage switching (ZVS). The auxiliary switch turns on with zero current switching (ZCS) and turns off with ZVS. In addition, the snubber cell does not create additional current or voltage stress on the main switches and main diodes. The proposed converter can smoothly achieve soft switching characteristics even under light load conditions. The theoretical analysis and operating stages of the proposed converter are made for the D > 50% and D < 50% modes. Finally, a prototype of the proposed converter is implemented, and the experimental results are given in detail for 500 W and 50 kHz. The overall efficiency of the proposed converter reached 95.5% at nominal output power.

“…The ZCS techniques have some drawbacks such as a significant voltage stress on main diode, which increases the conduction losses, and presence of the resonant inductor in series with the main switch, which increases the magnetic losses. The technique of zero voltage switching is applicable to all switching topologies ZVS technique [9]- [11]basically consists of forcing to zero the active switch voltage that prior to its turn-on by creating a resonance between an inductor and a capacitor. The inductor also limits the rate of variation of the diode current so losses due to the reverse recovery are reduced as well converter are simple topology, , fast transient response,high power density and continuous input current.…”
