“…The two-switch method has the lowest voltage stress, and the double-forward method has the highest efficiency [27][28][29][30]. In [31], an interleaved series input parallel output (ISIPO) forward converter was proposed. The ISIPO forward converter share many of the same features, including: 1) The voltage stress of each switch is clamped to the input voltage, which is the lowest voltage stress of all the forward topologies mentioned above.…”

“…Once the ZVS QRC converter is designed to achieve ZVS condition at light loads [29], the voltage stress on switches is extremely high at full load operating conditions. Likewise, for ZCS type QRC converters [31][32][33][34][35][36], the switch has a high capacitive turn-on loss due to the ZCS turn-on. Generally, voltage and current rms values are relatively high in resonantbased converters due to the sinusoidal voltage and current of the main components.…”

“…Interleaved pulse-width modulation (PWM) controller can control several converter cells with phase-shifted PWM technique to realise the load current sharing and ripple current cancellation. The parallel forward converters with soft switching techniques have been presented in [29][30][31][32][33] to realise ZVS operation and achieve conversion efficiency improvement. However, the control scheme is more difficult to implement, and many switches are used in the circuits.…”

Forward converters have been broadly used in the power supply industry due to their simplicity, worthy efficiency, and low cost. A novel prototype soft-switched zero-voltage and zero-current ZVZC PWM DC-DC power converter with low voltage/current stresses is introduced for telecommunication power feeding in this paper. A new two-switch interleaved forward converter circuit is introduced to minimalize current circulation with no supplementary auxiliary snubber circuits. This converter circuit includes some outstanding benefits such as reduced components, improved efficiency, high power density and economic circuit configurations for high power conditioning applications. The simple operation principle is demonstrated on the basis of steady-state analysis. Furthermore, the effective feasibility of the proposed circuit topology is evaluated and verified practically for a 500 W–100 kHz prototype breadboard. The operation principle and steady-state characteristics are demonstrated from a theoretical point of view. To verify the practical effectiveness of the proposed power converter, a 500 W–100 kHz prototype converter using ultrafast IGBTs is implemented for a distributed telecommunication energy plant. The studied soft-switching converter is evaluated in comparison with the previously-proposed PWM converters in terms of voltage, current stresses, and operating efficiency.

“…Here the transformers are parallel connected such that the power losses are equally distributed. It also uses interleaving architecture such that current ripple at the output side is minimized with maximum power density [4]. Nevertheless the voltage stress causes more losses in the circuit, hence [5] examined the parameters that affect the clamp voltage and from which critical parameters are identified and arrived at a mathematical solution for the clamp voltage.…”

A novel isolated dc-dc forward converter with a regenerative snubber circuit is introduced in this paper. Regenerative operation is achieved by effective utilization of the tertiary winding transformer. Due to easy control of the turn's ratio of the transformer, the capacitor gets easily charged which in turn improves the overall efficiency of the converter. The performance of the circuit is analyzed by simulation and using hardware. The proposed converter also achieves ZVS without any additional circuitry

“… Interleaved power converter stages can be used to reduce the output current ripple. With the forward converter in the continuous current mode, the ripple in the aggregate iout can be virtually eliminated by operating units in parallel at a duty cycle of 1/n or 1-1/n each [11] where n is the number of units. In [12], a pre-regulator buck converter stage varies the input voltage applied to units in parallel.…”

Recent advances in superconductors have led to their increased application in magnets and a requirement to carry ever-larger currents. This article describes the development and implementation of a cryogenic DC/DC converter for supplying a DC excitation current of 500 A for superconducting magnet applications. Practical aspects are addressed and the rationale behind selecting an interleaved forward converter topology is elucidated. Experimental results are given and a ripple content in the load current of less than 5% is estimated.
