Abstract With the increasing shortage of traditional energy resources, new resources such as fuel cells are widely used. However, front-end output voltage power generation systems is low, which cannot directly supply to load. Therefore, an efficient DC converter with a high boost ratio needed raise required level. The staggered parallel has characteristics small input current ripple and gain, v...

The DC-DC boost converter reveals highly non-linear and non-minimum phase properties, is very difficult task to design a controller that is healthy against load variation. For this purpose a Fuzzy PID Controller is proposed to control DC-DC boost converter which has a practical inductor and a series resistance. A balancing ProportionalIntegral-Differential (PID) controller to the parallel-dampe...

Input-series-output-parallel (ISOP) converters consisting of multiple modular DC/DC converters can enable low voltage rating switches to be used under high voltage input applications. This paper presents a digital control strategy, which can achieve equal sharing of input voltage for a modular ISOP system consisting of two-transistor forward DC/DC converters by forcing the input voltages of nei...

Arc phenomena are usually related to the undesired disengagement of two electrical connections. The emission power discharge from failure arc may damage wiring and can present a fire hazard. Numerous studies have been proposed detect events quickly isolate them an system. DC faults often sorted into types: series parallel arcs. A be outcome discharging links in wiring. By contrast, occurs betwe...

In this paper direct AC to DC is converted by proposed model from low AC voltage to high DC voltage in single stage conversion. And this paper presents an efficient AC to DC power that avoids the bridge rectification and directly converts low AC input voltage to high DC output voltage. This proposed converter consists boost converter and buck-boost converter both are connected in parallel to pr...

An easy dc-dc boost converter is unable to give high step-up voltage gains due to the effect of power switches, rectifier diodes, and the equivalent series resistance of inductor and capacitors. In this paper proposes new dc-dc converter to achieve high voltage gain without an extremely high duty ratio. In the proposed converters, two inductors with the same level of inductance are charged in p...

This paper presents an interleaved class E2 dc/dc converter. In the proposed converter, N class E2 dc/dc converters are connected in parallel at the class E rectifier. The proposed converter is suitable to the low-voltage/high-current applications. Since less current flows through the each converter, the amount of the power losses on the parasitic resistances are also reduced. In addition, the ...
