In high altitude wind power (HAWP) generating system, medium voltage AC (MV-AC) permanent magnet synchronous generator (PMSG) is used. The generated electrical power is transmitted to ground without any power conditioning in the air-borne unit. The ground based power conversion system (PCS) interfaces variable voltage and variable frequency medium voltage power into distribution level grid voltage...
High altitude wind power (HAWP) generating system poses several benefits over conventional wind power (CWP) generating system. An air-borne electric generator is held at high altitude above the ground surface with buoyancy provided by light gas filled blimp/aerostat. In order to minimize the size of the blimp and to reduce the number of electric components in the air-borne system, generation of electrical...
This paper presents a high power density DC-DC converter for electric propulsion of micro and nanosatellites. The front end of the proposed topology consists of a full-bridge LLC resonant converter. LLC resonant converter is particularly chosen since this resonant tank yields significant voltage boost without addition of external components to the resonant tank while operating in the lagging current...
This paper presents a high power density DC-DC converter for Radio Frequency (RF) transmitters. To meet the requirement of high voltage gain, LLC based converter followed by high frequency step up transformer and symmetrical quadrupler rectifier is proposed. The key advantage of using quadrupler in place of conventional rectifier and multiplier is discussed. The various modes of operation of converter...
An efficient solar energy harvester for low power wireless sensor node is proposed in this paper. In the proposed harvester, maximum power point tracking (MPPT) is achieved by using constant voltage tracking principle. The implementation of the MPPT control circuit is carried out using analog discrete components. This is to minimize the energy consumption in the electronic circuits. Experimental test...
