This paper proposes a high voltage ratio and low ripple interleaved boost DC-DC converter, which can be used to reduce the output voltage ripple. This converter transfers the low DC voltage of fuel cell to high DC voltage in DC link. The structure of the converter is parallel with two voltage-doublers boost converters by interleaving their output voltages to reduce the voltage ripple ratio. Bes...
Constant-current (CC) power supplies find applications in many fields. The Resonant immittance converters (RICs) convert a voltage source to the current source, thereby render them suitable for its application as a CC power supply. A fourthorder RIC topology, TT44 , is studied in this paper. Detailed steadystate analysis is presented. Procedure to perform converter optimization that leads to cl...
A method for designing power line filters for SMPS is presented. The practical design work is optimized, by excluding the nonviable combinations of filter components. The designer can choose among the theoretically viable combinations, to try practical designs. The theoretical calculations are based on chain parameters. As an illustration of the method a single stage π-filter for a buck convert...
Switched Capacitor DC-DC Converter: Superior where the Buck Converter has Dominated
In recent years, more research has been done on Enhancement Mode Gallium Nitride (eGaN) converters as the world is moving towards more power efficient converters. The process to make converters more efficient was bit complicated and slow in 20th century. With help of simulation tools such as MATLAB and LTspice, this process has become much faster and reliable in modern era. In order to make thi...
With a development of Hybrid Electric Vehicle(HEV), A photovoltaic(PV) generation system is used for charging batteries in many cases. A dc/dc converter using PV power for a battery charger requires a high efficiency. In this paper, A ZVS boost converter using the renewable energies for HEV charger is proposed. Through the theoretical analysis and experimental result, operation modes and charac...

The phase shift full bridge (PSFB) converter allows high efficiency power conversion at high frequencies through zero voltage switching (ZVS); the parasitic drain-to-source capacitance of the MOSFET is discharged by a resonant inductance before the switch is gated resulting in near zero turn-on switching losses. Typically, an extra inductance is added to the leakage inductance of a transformer ...
this paper presents a control strategy for fuel cell/energy storage power generation system during voltage sag conditions. the hybrid dc power sources are connected to grid using power electronic converters include dc-dc converter and grid connected voltage source inverter. the power from hybrid power sources is controlled during voltage sag by designing of control strategy for dc-dc converter....
The DC-DC converter topologies have received increasing attention in recent years for high power and high performance applications. The advantages of DC-DC boost converters include increased efficiency, reduced size, reduced electromagnetic emission, faster transient response, and improved reliability. The front end inductors in a boost converter are magnetically coupled to improve electrical p...
