Power electronic converter systems for applications such as telecom, automotive, and space can have dc voltage buses that are backed up with batteries or super-capacitors. These batteries or super-capacitors are connected to the buses with bidirectional dc–dc converters which allow them to discharged or charged, depending on the operating conditions. Bidirectional dc–dc converters may be isolat...

This paper explains the design of a standalone Solar/ Fuel cell/ Battery hybrid power system which involves the design of individual systems along with the power management circuit. The variation of solar insolation according to the time and the Maximum Power Point Tracking’s (MPPT) Perturb and Observe (P&O) algorithm is considered in the design of solar system. Similarly, the control of fuel f...

This paper presents a high step up DC-DC converter to boost low voltage PV system voltage. The switched capacitor converter can obtain a high voltage gain but the line and load regulation is poor and the output voltage is not regulated. The output regulation of the non isolated switching mode DC-DC converter is excellent but the voltage gain cannot be too high.A combination method of the SC con...

In this work, a non-isolated high step up DC-DC converter using coupled inductor and voltage multiplier cell is proposed. The proposed converter conversion ratio is efficiently extended by using a coupled inductor. An interleaved configuration of two diode-capacitor cells is applied to step up the voltage conversion ratio and decrease the voltage stress across the switches. Also, in the suggest...

DC-DC converters, common in battery-driven, portable, and other high-efficiency systems, can deliver efficiencies greater than 95% while boosting, reducing, or inverting supply voltages. Resistance in the power source is one of the most important factors that can limit efficiency. This application note describes the effects of source resistance, how to calculate efficiency, real-world considera...
