A high-gain non-isolated DC-DC converter is proposed with a inversely coupled inductor and a voltage lift cell. Energy stored in the leakage inductance of the coupled inductor is recycled through a voltage lift cell to obtain high voltage conversion ratio. The operation of the proposed converter is explained using its equivalent circuits which are used to derive static gain expression. The operation...
In the present scenario, electricity generation from waste heat has become an attractive option in both research and industrial sectors. Conventional waste heat recovering techniques mostly use ThermoElectric Generators (TEG), for conversion of heat energy into electrical energy. In this paper a non-isolated high step-up DC-DC power converter with switched capacitor cells is proposed for the ThermoElectric...
This work deals with the design and a prototype implementation of a maximum power point tracker (MPPT) for a thermoelectric (TE) module aiming to improve energy conversion efficiency in battery charging. This system uses TE devices that directly convert heat energy from a water gas heater to electricity to charge a battery. The TE module exhibits a non-linear I-V characteristic and its maximum power...
