A technique which improves the performance of the boost converter by reducing the reverse-recovery-related losses in the boost switch and rectifier with an active snubber that is implemented with a minimum number of components is presented. This minimum-component-count snubber consists of a snubber inductor, an auxiliary switch, and a rectifier. The proposed technique reduces the reverse-recove...

In this paper, we propose a novel reverse converter for the moduli set {2n + 1, 2n, 2n − 1}. First, we simplify the Chinese Remainder Theorem in order to obtain a reverse converter that uses mod(2n−1) operations. Next, we present a low complexity implementation that does not require the explicit use of modulo operation in the conversion process and we prove that theoretically speaking it outper...

This paper presents a high-efficiency nonisolated interleaved dc–dc inductor boost converter with a common active clamp circuit. Interleaved boost converters are highly preferred as it reduces the ripple current. A boost converter is used to clamp the voltage stresses of all the switches in the interleaved converter which is caused by the leakage inductances. The leakage energies of the interle...

In this work, a non-isolated high step up DC-DC converter using coupled inductor and voltage multiplier cell is proposed. The proposed converter conversion ratio is efficiently extended by using a coupled inductor. An interleaved configuration of two diode-capacitor cells is applied to step up the voltage conversion ratio and decrease the voltage stress across the switches. Also, in the suggest...

In this paper, we introduce a new 6n bit Dynamic Range Moduli set { 2 2n , 2 2n + 1, 2 2n – 1} and then present its associated novel reverse converters. First, we simplify the Chinese Remainder Theorem in order to obtain an efficient reverse converter which is completely memory less and adder based. Next, we present a low complexity implementation that does not require the explicit use of modul...

This work presents the analysis of radiated EMI problems associated with DC-DC buck converters and the solutions for minimize the reverse recovery of the Drain-Bulk diode of the synchronous switching MOSFET. The DC-DC buck converter topology is used in computers and telecom applications because of its high power efficiency and multiple DC levels. For reducing the reverse recovery and its relate...

The residue number system (RNS) is an integer system capable of supporting high speed concurrent arithmetic. One of the most important consideration when designing RNS system is reverse conversion. The reverse converter for recently proposed for the four-moduli set {2n −1,2n,2n +1,22n+1 −1} is based on new Chinese remainder theorems II (New CRT-II) [6]. This paper presents an alternative archit...

In last years, many modulus sets in the Residue Number System (RNS) for increasing Dynamic Range (DR) and parallelism are presented. Hence, for reach these purposes a new 5-Moduli Set for even n, and its efficient reverse converter design are introduced in this paper. This modulus set contains pair-wise relatively prime, and it offers the maximum feasible DR. New CRT-I and MRC are used to obtai...

In the present simulation work, an attempt is made to study the switching dynamics of an optically controlled 4HSiC thyristor power semiconductor device with the use of GaAs optically triggered power transistor. The half-cell thyristor has the forward breakdown of 200 V and reverse breakdown of more than 1000 V. The optically controlled thyristor has a rise time of 0.14 μs and fall time of 0.06...

-A dc-dc converter has its applications, such as in hybrid vehicles, solar inverters, in power supplies for microprocessors etc. A bidirectional dc-dc converter can be alternately operated as a step down converter in one direction of energy flow and as step up converter in reverse direction of energy flow, in places where both the sides have voltage sources. A high voltage supply using a single...
