This paper presents the supercapacitor power management method for the Hybrid Electricals Vehicles.A simple zero-voltage switching(ZVS) interleaved boost power factor correction(PFC) AC/DC converter is used to charge the traction battery of an Hybrid Electrical Vehicle. The auxiliary circuit provides limited current to charge and discharge the MOSFETs output capacitors during turn-On times at z...

Interleaving can be thought of as a method of paralleling converters but it has got additional benefits to offer in addition to those obtained from conventional approaches of paralleling converters. Interleaved converters due to its simple structure and low control complexity are widely used in applications where non-isolation and high output current with low ripples are required. They have got...

Single-Stage transformerless AC/DC converter received much attention in the universal line application. Unlike the existing converters a new high step-down transformerless single-stage single-switch AC/DC converter is proposed. The topology integrates a buck-buck-boost converter with low intermediate bus and output voltage. The converter utilizes a buck converter as a PFC cell and buck-boost co...

This paper investigates the effect of the variation of duty ratio on the different performance parameters of the three non-isolated dc-dc converters namely buck, boost and buck-boost converter. Five important parameters dependent on the duty ratio have been identified namely output voltage, output current, effective impedance at the input, minimum inductance and minimum capacitance for continuo...

In this paper, a new transformerless buck-boost converter based on ZETA converter is introduced. The proposed converter has the ZETA converter advantages such as, buck-boost capability and input to output DC insulation. The suggested converter voltage gain is higher than the classic ZETA converter. In the presented converter, only one main switch is utilized. The proposed converter offers low v...

In this paper, a novel converter topology for interleaved high step-down conversion ratio dc–dc converter with low switch voltage stress is proposed. In the proposed converter, two input capacitors are series-charged by the input voltage source and parallel discharged by a new twophase interleaved buck converter topology without adopting an extreme short duty cycle for delivering a much higher ...

This paper shows a three-phase series resonant DC-DC boost converter simulation model with double LLC tanks (SRC-W-DLLC-RTs) for hybrid solar wind system (HSWS) battery energy storage DC load. An intrinsic drawback of solar-wind technology is its intermittent and weather-dependent output voltage. MPPT control algorithm-based converter, which offers interfaces between load, can overcome this iss...

This paper proposes a multi-stage power generation system suitable for renewable energy sources, which is composed of a DC-DC power converter and a three-phase inverter. The DC-DC power converter is a boost converter to convert the output voltage of the DC source into two voltage sources. The DC-DC converter has two switches operates like a continuous conduction mode. The input current of DC-DC...

One of the most efficient lighting technology is based on light-emitting diodes (LEDs). Common LED drivers with AC-input (50-60Hz) usually require a bulk electrolytic capacitor to decrease low-frequency ripple in the output. However, the critical element that limits the lifespan of the LED driver is the electrolytic capacitor. An isolated off-line LED driver is proposed in this paper, in which ...
