Wireless power transfer requires multilevel energy conversion for energy transfer, resulting in a bulky system. This paper proposes a direct AC-AC converter topology denoted as double half-bridge series-matrix converter and introduces a symmetric modulation method that eliminates the need for input voltage polarity detection. The converter circumvents DC conversion and operates at a unit power factor without the assistance of power factor correction. A 1kw prototype was constructed and the same control strategy was adopted, without considering the polarity or magnitude of the input voltage, verifying the accuracy and reliability of the proposed topology. The transmission efficiency was achieved at 91.43%.

“…Various topological techniques [9] and control strategies [10,11], are studied with the purpose of achieving a constant current. Complex control methods for wireless systems are used to regulate output under different load conditions [12][13][14]. High energy losses, the need to use sensors, and large space to build can be the most important limitations of these methods [15,16].…”

In current study, a method for achieving a load-independent output current with the ability to optimize the parameter tuning, which is applied to wireless power transfer (WPT) systems, is analyzed. The proposed technique is based on the immittance property in a passive resonant network (PRN) with the purpose of transforming a voltage/current resource into a current/voltage resource. This study determines an immittance conditions-qualified family of PRN, which is associated with a more appropriate topological description in WPT applications. Considering the resource and sink type, a comprehensive specification of the coupling coefficient-based design condition and operating point is carried out. Moreover, the parameters of each proposed topology are reconfigured by adjusting the proportion of active power to reactive power ratios as an index to optimize the topology size as well as a reduction of voltage/current stresses on their elements without changing the specified system-level parameters, such as the loosely coupled transformer operating frequency, and specified constant current outputs. The sample topology selection is also carried out with respect to the absorption of the parasitic components and achieving the inherent dc-blocked transformer. Zero-voltage-switching (ZVS) operation of the switches, minimum conduction losses of the rectifier diodes within an extensive variety of load variations, and capability of consistent generation of stable load-regulated current are also achieved. Analytical results show that the proposed compensation has the minimum output current fluctuation versus variations of the coupling coefficient and other parameters. Finally, the effectiveness of the proposed methodology is evaluated through simulations, and practical experiments, and compared with the conventional design method.

“…The current source property is obtained without using any feedback loop and only by configuring the resonant tank. In [6], all possible combinations of the resonant tank with three resonant elements have been analysed. It is shown that a particular combination of the LCC resonant tank behaves as a constant current source at 1:4x n (where x n is the normalised switching frequency).…”

Analysis and design of efficient SiC-based load-resonant converter with advanced features for arc welding applications

et al. 2021

This letter presents a novel and efficient SiC-based harmonic-current-assisted LCC load-resonant converter for arc welding applications. A higher OCV, required for arc strike, can be obtained by using the harmonic gain of the resonant network at no-load condition. Resonant elements have been designed to reduce the input DC voltage to about half compared to that in a quasi-resonant converter. This reduces the core losses of the isolation transformer. The efficiency of the converter is further increased by ensuring ZVS operation of the switching devices, irrespective of load variations. The self inductance of the lead wires make the selection of the resonant elements an interesting exercise. A Finite element (FE) based simulation is used to determine the leakage inductance. The converter is fabricated in the laboratory and the experiments are conducted up to 1.0 kW load. Excellent mutual agreement between simulated and experimental results upholds the accuracy of the FE modelling and estimation of the lead inductances with the preciseness of the experimental set-up.
