This paper presents a boost converter along with a flyback converter. The Zero Voltage Switching (ZVS) technique is used to achieve soft switching. A bidirectional boost converter is connected with an output module as a Parallel Input Serial Output configuration. The flyback converter with Voltage Doubler Rectifier (VDR) acts as an output module. This connection makes a bidirectional boost conv...

Abstract. This paper proposes a novel soft-switching dual full-bridge converter with shared lagging leg and dual outputs in series. Resonant clamp circuits are employed across the secondary rectifiers to reduce the voltage overshoots of the secondary rectifiers, as well as extinguish the primary current during the freewheeling interval. Full Zero-Voltage-Switching (ZVS) range of the lagging leg...

PWM inverter systems have been used in many industrial processes in order to control voltage, frequency and harmonic. On the other hand, High Frequency Resonant DC Link Inverters have been proposed to reduce the switching losses of power devices.

A new resonant switch is introduced which employs nonlinear tank elements. Zero current switching is obtained. yet the peak transistor voltage and current stresses can approach those of an equivalent ideal PWM converter. Reduced switching loss without a substantial increase in conductbn loss is therefore possible. An approximate analysis is outlined, and transistorpeak voltage and current stres...

The purpose of this paper is to introduce a new family of zero-voltage switching (ZVS) pulse-width modulation (PWM) active-clamping dc-to-dc boost converters. This technique presents ZVS commutation without additional voltage stress and a significant increase in the circulating reactive energy throughout the converters. So, the efficiency and the power density become advantages when compared to...

This paper presents simplified space vector pulse width modulation (SVPWM) based vector controlled induction motor drive. The conventional SVPWM algorithm constructs the required voltage vector in the average sense by using active and zero voltage vectors. Moreover, complexity involved in conventional SVPWM algorithm is more. Whereas, the proposed SVPWM algorithm calculates the switching times ...

For Silicon devices, the forward voltage drop of the pn-junction rectifier can not be reduced below about 0.8 volts even if the device is not required to block higher reverse voltage. In the case of the output rectifiers used in power supplies for computers and telecommunications, this voltage drop is a large fraction of the output voltage of 5V or less. This results in a loss in the power supp...

A comparison study was conducted to characterize the loss mechanisms, component stresses, and overall efficiencies of a group of voltage-mode softswitching PWM methods including two newly developed methods. All soft-switching methods in the selected group allow zero voltage turn-on and turn-off of the main switch and utilize a single auxiliary switch with some resonant components. Advantages an...
