-In recent years, the development of new technologies is requiring power supplies with wide dc conversion range. In this paper an alternative solution is presented, the properties of the new soft-single-switched (SSS) Boost converter with voltage ratio that are quadratically dependent on duty cycle are discussed. The converter is a zero-current-switching (ZCS) during the turn-on period and a zero-voltage-switching (ZVS) during the turn-off period. The operating principle of the proposed converter is explained; its operating modes along with key waveforms are shown. Moreover, a complete simulation and experimental results have verified the feasibility of its applications in renewable energy systems. 1

“…This group of converters is called soft switching PWM converters; an example of these converters is presented in [17]. In the soft switching PWM converters, the switches operate in resonant mode only during switching transitions and then, return to PWM operation for the rest of a switching period.…”

“…It has the merit of establishing of high output voltage, high power factor, improved efficiency and fewer harmonic as mentioned in [1], [2]. The limitations in the soft switching can be tackled by means of interleaved converters [3]. The proposed interleaved boost converter has less input ripple current, reduced I 2 R losses with lower rating of the switch and provides increased system reliability.…”

Abstract:In this work, time domain based discrete controlled Pulse Width Modulated Interleaved Boost converter has been formulated. To achieve the desired closed loop response of the system controller, precise information about the open loop response is vital. In Industries, discrete controller is preferred than other controller, as it will not demand analytical model of the system that has to be controlled. The proposed controller is used to improve the dynamic performance of the Interleaved Boost Converter by achieving a robust output voltage against varying load disturbances, fluctuations in input voltage and deviations in circuit components. The discrete controller is implemented experimentally and the observed results substantiate better mapping between the design goals and the experimentally identified response.

“…The normal zero voltage transition (ZVT) PWM converter [15] had been presented to implement the ZVS turn on process of the main switch during a very short ZVT time provided with a resonance. Recently, a zero voltage transition (ZVT) commutation cell was presented in [16] to provide ZVT for the main switch. It has many good features, then it was used to propose a ZVT Boost PWM converter featuring voltage conversion ratio with quadratic dependence on the duty cycle.…”

In this paper, a new active snubber cell is proposed to contrive a new quadratic Boost pulse width modulated (PWM) converter. This snubber cell provides zero voltage transition (ZVT) for the main switch of a converter. A New ZVT-PWM Quadratic Boost converter equipped with the proposed snubber cell provides most the desirable features of ZVT converters presented previously, and overcomes most the drawbacks of these converters providing a large voltage step-up. Subsequently, the new converter can operate with soft switching successfully at very wide line and load ranges and at considerably high frequencies. Moreover, the main devices do not have any additional voltage and current stresses. In this study, a detailed analysis of the new converter is presented, and this theoretical analysis is verified exactly by simulation and a prototype converter.
