“…The interval duration is determined by the instant the resonant capacitor voltage tends to reverse polarity, thus forward polarizing the other switch body-diode (D b ). From (13), we can derive: (14) Interval t 3 ≤ t ≤ s (see Fig. 2(c)).…”

“…As already known, the major drawbacks of passive snubbers are the duty-cycle limitation due to the time needed to reset their condition at each commutation, and the increased switch current stress. These aspects can be mitigated by using active soft-switching cells, like in [6]- [14]. In some of these examples, like in [7], [10], [11] and [14], the auxiliary switch drain-source voltage is not clamped, thus exposing it to high frequency ringing and possible overvoltage.…”

This paper presents the detailed analysis and design of a soft-switching DC-DC converter called clamped-resonant interleaved boost converter (CRIB). This topology, thanks to a resonant L-C tank connected between the drain terminals of the switches of two interleaved boost cells, achieves zero-voltage and zero current commutations of all devices, independently of the load current, with a reduced dv/dt across the switches, making the converter suitable for high-frequency operation. Moreover, a proper no-load operation is proved, whenever the minimum voltage gain is higher than a given threshold. Differently from previous works on current-fed resonant converters, the presented theoretical analysis includes the effect of the input filter inductors, allowing to derive a simple design procedure to meet the given specifications. According to the outlined design steps, an experimental prototype was built, rated at 42~54 V to 400 V~300 W. Measurements confirm the theoretical predictions, showing an efficiency above 96% at the nominal power in the whole input voltage range. Finally, the possibility to reduce the overall magnetic volume by coupling the two input inductors is demonstrated.

“…Soft-switching methods for these converters can either be zero-voltage switching (ZVS) if they are implemented with MOSFETs or zero-current switching (ZCS) if implemented with IGBTs. The focus of the paper is on ZCS methods for IGBT converters [18][19][20], [22][23][24][25], [27][28][29][30][31][32][33][34]. Most of these, use an auxiliary circuit that is activated whenever a main converter switch is about to be turned off, gradually diverting current away from the switch so that it can turn off with ZCS.…”

“…With more components in the main path of current, conduction losses are increased, and the auxiliary circuit components need to be implemented with higher current rated components.

An AC-DC Interleaved ZCS-PWM Boost Converter With Reduced Auxiliary Switch RMS Current Stress

et al. 2021

The paper proposes a novel interleaved AC-DC ZCS-PWM boost converter that requires the use of just a single active auxiliary switch to assist in the turning off the main power circuit switches with ZCS. The auxiliary switch can be turned on and off with ZCS and its auxiliary circuit allows the converter to operate without an increase in the main switch peak current or voltage stress. The auxiliary switch in the converter is active for a much shorter time than in most other ZCS-PWM converter, which allows the converter to operate at higher power levels than other previously proposed interleaved ZCS-PWM converter with a single auxiliary switch. The proposed converter's operation is explained in the paper and its key features and design considerations are discussed. Experimental results that confirm the operation of the proposed converter are presented as well.

“…An interleaved circuit topology integrates more power converters connected in parallel [9][10][11][12]. The switching operations for the power converters are interleaved so the effective switching frequency is multiplied and the power capacity of the output filter is reduced.…”

This study proposes an interleaved multi-level power converter (IMPC) for a battery energy storage system. The proposed IMPC is composed of two power-electronic legs. The first power-electronic leg is an interleaved multi-level leg that contains eight power-electronic switches. Four power-electronic switches constitute a two-phase interleaved switch set and these are switched in a high-frequency interleaved pulse-width modulation. The other four power-electronic switches constitute a level-selection switch set that determines the dc bus voltage for the two-phase interleaved switch set according to the magnitude of the utility voltage. The second power-electronic leg is the low-frequency switching leg, which is composed of two power-electronic switches. Since the proposed IMPC integrates the performances of the multi-level power converter and interleaved power converter, the effective switching frequency is twice the practical switching frequency and the output voltage has five voltage levels. The ripple of the output current is significantly attenuated and the power capacity of the output filter is reduced. The proposed IMPC can also be used to adjust the real and the reactive power flows, in order to control the charging/ discharging of battery sets and to compensate for the reactive power. A hardware prototype is developed to verify the performance of the proposed IMPC.
