A family of single-stage converters called Reconfigurable Solar Converter (RSC) is presented for integration of energy storage with a PV system where ramp-rate control and peak-shifting is desired. An algorithm designed to reduce the variability of photovoltaic (PV) power output by using a battery demonstrates the PV power output smoothing. The purpose of the battery is to add power to the PV output...
This paper investigates magnetic couplers which could potentially be installed within or around a kickstand of an electric bicycle to provide wireless charging capability to the bicycle. The bicycle kickstands considered were the side stand and bracket stand. A cylindrical solenoidal pickup and a solenoidal bar pickup are proposed to be housed in the side stand and bracket stand respectively. Two...
Electric Vehicles (EVs) are quickly gaining widespread interest as attractive alternatives to conventional petrol driven vehicles. If EVs can derive some or all of their electrical power from renewable sources, then they can significantly help to reduce global dependence on fossil fuels for transportation. Inductive power transfer (IPT) is a method that can transfer power to EVs over an air-gap without...
This paper discusses the characteristics of a series-series compensated inductive power transfer system (IPT) with theoretical analysis and experimental results. To maximize system efficiency, two-stage structure, which includes a PFC stage and a resonant DC-DC stage operating in ZVS region, is proposed. One of the major design challenges in implementation of a practical contactless EV charger is...
This paper presents the feasibility study of bipolar pads for extremely high efficiency wireless battery chargers used in electric vehicle (EV) and plug-in hybrid electric vehicle (PHEV) applications. Due to the unconventional flux distribution in this system, a 3D finite element method was employed for its design and analysis. The importance of misalignment tolerance in this system is analyzed and...
