In this paper, a hybrid control strategy is studied and implemented on an Inductive Power Transfer (IPT) system to simultaneously realize zero-voltage switching (ZVS) constant current (CC) voltage (CV) battery charging. A steady-state analysis of pulse frequency modulation was conducted, based the characteristic gain versus frequency, CC CV charging modes were promised. The ZVS inverter obtaine...
a new output structure for class e power amplifier (pa) is proposed in this paper. a series lc resonator circuit, tuned near the second harmonic of the operating frequency is added to the output circuit. this resonator causes low impedance at the second harmonic. the output circuit is designed to shape the switch voltage of the class e amplifier and lower the voltage stress of the transistor. t...
In this paper, based on the switching-cell approach, a generalized steady state analysis for families of soft-switching dc-todc converters will be presented. Complete generalized design equations will also be given. The concept of generalization and step by step procedure for the generalized process are discussed and applied to selected soft-switching families such as ZVS-QRC, ZCSQRC, QSW-CC, Q...
Several new schemes for constructing 3 lowharmonic rectifiers are introduced here. These 3 ac–dc topologies are derived from parent dc–dc converter topologies. With a single active switch featuring the zero-voltage switching (ZVS) property in addition to the diode-rectifier bridge, the rectifiers are capable of naturally drawing approximately sinusoidal input-current waveforms at nearly unity p...
This paper represents a comparative study of isolated resonant topologies for photovoltaic application such as half bridge, full bridge and push pull topology. The performance of these topologies is analyzed with the help of Pulse Width Modulation (PWM) technique. The stressful behavior of the switches is reduced by soft switching technique. So, the primary side switches utilize zero voltage sw...
This paper introduces eight novel interleaved non-isolated dc-dc converters with ultra-high step-up and zero voltage switching (ZVS) capabilities for renewable energy systems. To increase the gain, proposed benefit coupled inductors, high-frequency (HF) transformer, multiplier (VM) techniques. In comparison to other converters, which just inductors or HF transformers, these combinations of tech...
