Email this article Fuel Cell Based Bridgeless Boost Rectifier For Low Voltage Energy Harvesting Applications
Abstract
energy producing systems power electronic circuit figures the key boundary between transducer and electronic load which might embrace a battery. The electrical and physical description of the power conditioning interfaces establishes the functionality, competence and the size of the integrated systems. The power electronic circuits are engaged to legalize the power delivered to the load and vigorously direct the electrical humid of the transducers so that maximum power could be transferred to the load. The output voltage level of the micro scale and mesoscale energy return devices is more often than not in the order of a few hundred millivolts depending on the topology of device. To get voltage for medium order in volts we introduce Fuel cell. The output ac voltage should be rectified, boosted and synchronized by power converters to complete the voltage requirement of the loads. The proposed topology unites a boost converter and a buck-boost converter to condition the positive and negative half portions of the input ac voltage respectively. Only one inductor and capacitor are used in both circuitries to decrease the size of the converter. A fuel cell is a device that converts chemical reaction into electricity. For generation of electricity hydrogen plays major role. Fuel cell efficiencies can reach 80-90% and stay clean for the environment. Versatile fuel cells offer a promising way to generate electricity and on a infinitely decentralized basis.
