The proposed converter accommodates a wide source voltage range to cover several sources to interface through extended secondary-circuit and hybrid modulation. Proposed fixed frequency hybrid modulation and design achieves soft-switching of semiconductor devices under all operating conditions. It is therefore suitable to be universally adopted for solar photovoltaic (PV), fuel cell, and battery applications. Current-fed technology is suitable for such sources (low voltage, high current). Experimental results are illustrated to verify the claims and to show the performance of the converter over a wide input voltage range of 20– 60 V with load variation

It has been a challenge to design a universal converter that is promising for interfacing different sources with different operating voltage ranges. In addition, maintaining soft-switching of semiconductor devices at high frequency (HF) while achieving high efficiency is another challenge. HF operation offers obvious merits of a compact and lightweight system. Voltage-fed converters have several issues such as rectifier diode ringing, duty cycle loss, etc., and are not suited for high-gain and high-current applications. Soft-switching can be achieved using additional components but at the cost of increasing the topology’s complexity with a limited soft-switching range In this paper, an extended secondary universal current-fed converter (ESUC) is proposed that operates with ZVS and zerocurrentswitching (ZCS) and can achieve output voltage regulation with a wide input voltage and load variation. The converter is claimed to be universal as it can accommodate input voltage variations in the ratio of 1 : 3 compared with conventional converters. Moreover, the range can be further extended by slight modifications in secondary-circuit design. Thus, it is seen as a potential candidate for interfacing solar panels (20–42 V), fuel cells (22–41 V), and batteries (24/36/48/60 V) with load. To achieve load voltage regulation, hybrid fixed frequency modulation is proposed.

For input voltage of 40–60 V, the duty cycle of primary-circuit devices is fixed at 55%, whereas the duty cycle of the secondary devices is varied to regulate the load voltage, i.e., full or partial utilization of the secondary side. It makes the proposed converter promising for different sources with different voltage ranges.

Voltage across the switches is clamped without an active clamp or passive snubber. It makes a reduction in size and cost. It improves the converter efficiency by ZCS of primary devices, zero-current turn-on of all devices, and natural commutation of secondary diodes and body diodes of primary devices. Switching transition losses are significantly reduced. It has negligible circulating current and lower conduction losses and, therefore, is expected to show better light load efficiency than hard switching

The range can be further converter for different operating conditions. extended by modifying secondary-circuit design. Magnetizingminductance assists in maintaining ZVS of the primary switches over this range. The secondary switches operate with ZCS, thus minimizing the overall switching losses. The inherent current sharing property of a two-inductor topology and a high Lp/Ls ratio reduces the current stress on the devices compared with voltage-fed pulsewidth modulated and resonant soft-switching converters. Proposed hybrid modulation ensures load voltage regulation over wide input voltage and load variation. Above all, a single converter can be used for different sources such as batteries, fuel cells, solar PVs, etc.; therefore, it can be used in several applications such as microgrid and distributed generation. The analysis and design of the converter have been reported. Performance has been demonstrated through experimental results.
