“…A bridgeless rectifier using the boost-full-bridge with current source output characteristic was proposed as a single stage switch mode power supply (SMPS) in [13]. The SMPS application presents low output voltage (V o =48 V) and the output inductor filter is designed for the full-bridge operation in CCM at nominal output power.…”

“…The SMPS application presents low output voltage (V o =48 V) and the output inductor filter is designed for the full-bridge operation in CCM at nominal output power. A two duty-cycle modulation was proposed in [13] for the boost-full-bridge rectifier in order to comply with the SMPS application requirements using a single stage converter. A duty-cycle defined by the simultaneous conduction period of the diagonal switches of the full-bridge are used to control the output voltage.…”

“…However, the two duty-cycles modulation are not independent and one modulation limits the action of the other, imposing design and operation restrictions [13]. Some undesirable operation characteristics are the large primary side DC-bus voltage variation, input power factor reduction and harmonic distortion increment with the load and input voltage variations, input zero current cross distortion and operational problems at light load.…”

“…It is well known that the primary current is significantly affected by the transformer turns ratio n [1]. Since the oscillation amplitude is positively correlated with the peak current of the primary side, the transformer ratio should be designed while carefully considering the primary RMS current and the duty cycle loss [24]. Moreover, the transformer turns ratio has an effect on the signal analysis.…”

This paper presents a comprehensive analysis of the spurious turn-on phenomena in phase-shifted full-bridge (PSFB) converters. The conventional analysis of the spurious turn-on phenomenon does not establish in the PSFB converter as realizing zero voltage switching (ZVS). Firstly, a circuit model is proposed taking into account the parasitic capacitors and inductors of the transistors, as well as the parasitic elements of the power circuit loop. Second, an exhaustive investigation into the impact of all these parasitic elements on the spurious turn-on is conducted. It has been found that the spurious turn-on phenomenon is mainly attributed to the parasitic inductors of the power circuit loop, while the parasitic inductors of the transistors have a weak impact on this phenomenon. In addition, the operation principle of the PSFB converter makes the leading and lagging legs have distinguished differences with respect to the spurious turn-on problems. Design guidelines are given based on the theoretical analysis. Finally, detailed simulation and experimental results obtained with a 1.5 kW PSFB converter are given to validate proposed analysis.

“…The drawback associated with two stage PFC method motivated several researchers to find other way to provide both input current shaping and voltage regulation. Thus a new class of single stage power factor correction (SS-PFC) topologies has been presented [6,7,8,9].The voltage fed, single stage PWM full bridge converter shown in fig. 1 seen to be the most promising single stage converters.…”

ABSTRACT:Voltage fed single stage converters suffer from two main drawbacks: The efficiency is affected due to the reduced values of maximum DC link capacitor voltage and the power factor is not close to unity. To overcome these drawbacks, a boost type -input current shaping converter, integrated with diode clamped topology is used. Since this converter is a multilevel converter, it can be operated with high DC bus voltage. The power factor is also maintained close to unity. This converter is made to operate with fuzzy logic controller to regulate the output voltage. The fuzzy logic controller is designed and the performance of the ac-dc converter is tested using MATLAB/SIMULINK based closed loop simulation.
