Recently, an AC processing pickup has been proposed and used in range of applications from stage lighting to EV charging. This new pickup has the advantage of producing high efficiency AC output while retaining a simple circuit topology. However, the exactly analysis of these pickups has been rather difficult and time domain solutions in the form of transcendental equations are required to numerically...
This paper investigates a direct AC-AC IPT system which takes 50Hz mains input and generates 50Hz mains output without requiring a DC link in conventional systems. This technique is based on matrix converters giving advantages of low energy storage. The AC processing control concept is used to produce a controllable AC output. Preliminary simulation results have verified the operation of such a system.
This paper presents a 1kW inductive charging system for Electric Vehicles (EV's). The primary topology uses an LCL converter and the secondary topology uses a parallel AC processing pickup to produce a controllable current source ideal for EV battery charging applications. Standard circular pads with a diameter of 420mm were used. The system can operate over a variable charging height of 45–90mm....
This paper presents a 1.2 kW Inductive Power Transfer (IPT) lighting system using the parallel AC processing pickup. The AC processing pickup has been shown as an efficient and economic approach for producing high frequency AC outputs. IPT technology provides electrical power in a contactless manner, allowing multiple 1.2kW stage lights to be configured anywhere along the IPT track. This significantly...
This paper presents a new type of inductive power transfer (IPT) pickup that directly regulates the power in ac form, hence producing a controllable high-frequency ac source suitable for lighting applications. The pickup has significant advantages in terms of increasing system efficiency, reducing pickup size, and lowering production cost compared to traditional pickups that also produce a controlled...
