Solar energy is the most promising non-conventional sources of energy. This paper proposes the working of single phase induction motor using solar arrays and power electronics. The SEPIC converter is taken as dc-dc converter which is designed and DC analysis has been done in CCM. Then inverter is used to convert dc power to ac power. The performance of SEPIC converter and inverter is measured, ...

The boost topology is the most popular topology used in power factor correction circuits. The efficiency and performance of the boost converter depends on the switching frequency affecting the switching losses. At high frequency operations the switching losses of the converter is considerable and decreases the efficiency of the converter. To remove this problem the converter is designed to oper...

Portable electronic devices not only require switching DC-DC converters to be compact and integrated but also compliant to wide off-chip LC filter variations, which are subject to manufacturing tolerances, temporal and thermal parameter drifts, and more often than not, application-driven constraints. While optimal LC compliance has been demonstrated in ΣΔ buck converters, little has been done i...

Photovoltaic (PV) cell converts sunrays into electrical energy, which has non-linear I-V characteristics. For extracting maximum power from photovoltaic (PV) array for varying environmental conditions, it is necessary to use MPPT tracker. The MPPT consists of DC-DC converter and MPPT algorithm, DC-DC converter is inserted between solar panel and load or battery. The task of MPPT tracker is to m...

This paper proposes a new solar power generation system, which is composed of a DC/DC power converter and a new seven-level inverter. The DC/DC power converter integrates a DC-DC boost converter and a transformer to convert the output voltage of the solar cell array into two independent voltage sources with multiple relationships. This new seven-level inverter is configured using a capacitor se...

This paper deals with the simulation of closed loop and open loop controlled Interleaved Boost Converter (ILBC). It is seen that, for higher power applications, more modules can be paralleled to increase the power rating and the dynamic performance. One of the challenge in designing a boost converter for high power application is how to handle the high current at the input side. In this paper a...

Single-stage AC-DC converters integrate an AC-DC front-end converter with a DC-DC backend converter. Compared with conventional two-stage AC-DC converters, single-stage ACDC converters use less components and only one controller, which is used to regulate the output voltage. As a result, the cost, size and complexity of AC-DC converters can be reduced, but single-stage converters do not perform...

High power and high voltage gain DC-DC converters are key to high-voltage DC (HVDC) power transmission for offshore wind power.
