“…In this particular system, a multiple-phase push-pull inverter generating phase quadrature primary currents is used. This is different to the typical threephase converter [23] as the currents here need to be 90 degrees out of phase. These currents must be distributed along a 3D This article has been accepted for publication in a future issue of this journal, but has not been fully edited.…”

The industrial use of inductive power transfer systems is becoming widespread ranging from monorail systems, motors, people-movers and battery charging applications. This paper proposes a three-dimensional inductive power transfer system driven by a multiple phase power converter. This is aided by spice circuitry simulation of the power converter, finiteelement-assisted software magnetic frequency analysis and via implementation of the proposed system. The proposed system consists of a cubic power transfer primary window generated by a rotating magnetic flux flow path. This rotating field is loosely coupled via magneto-motive force induction into a secondary power pick-up. The system has been demonstrated as a lowpower battery charging system.

“…Therefore, the circuit design is to comprehend the amplitude of V loop and IEEE TRANSACTIONS ON INDUSTRIAL ELECTRONICS I loop to, by which the ratios of K CR and K VR are obtained. For example, when the plasma jet discharges 20W power, the voltage V loop becomes near 80V based on (12) and (13). Then, by setting K PR and V reg to be 2 and 2V, the K CR =2 and K VR =0.00625 are achieved.…”

This paper proposes a plasma-driven system with piezoelectric transformer-based feedback control approaches along with a contactless power source. The research is motivated because many plasma-driven circuits employed the bulky components as resonant circuit and current feedback sensors. Hence, this study proposes to utilize one piezoelectric ceramic transformer to serve for both resonance tank and feedback devices in order to achieve the low cost and design simplification. Moreover, since the plasma discharge often suffers the problem of high humidity and particle-polluted environment, a contactless power transfer circuit integrated with a high-frequency coil is developed as the power source, by which the electrode damage can be better prevented. To reach a better discharge quality and own a higher flexibility of regulating power, the study also completes a constant-power control mechanism and a phase-locked loop control. Both software simulations and hardware realization have been accomplished. Analysis results and experimental outcome help validate the practicality of the proposed approach.Index Terms-Plasma discharge, piezoelectric transformer, contactless power transfer, phase-locked loop control.

“…They also help to drive poly phase coils to generate rotating magnetic fields for applications such as contactless sliprings for rotary shafts [1,2], poly-phase homogeneous wireless power transfer systems [6,7], and 3D Omni-directional wireless power transfer systems [4]. The poly phase converters have also been used in radio frequency applications providing a ring-coupled oscillator as high frequency power sources [8,9].…”

Although the method is valid for multiple phases, a three phase system is studied to show accurate 120º phase shift can be realised by coupling 3 identical magnetic coils of a resonant converter with Zero Voltage Switching (ZVS). Unlike the conventional converters, the proposed converter achieves a full autonomous operation with automatic start-up, full resonance at ZVS, and accurate dynamic balancing between the phases without any additional detection and control. A prototype of a three phase system operating at 73.5 kHz has been built, and both simulation and practical results have demonstrated that the proposed converter can generate good quality sinusoidal waveforms with ZVS operation and precise phase delays. The proposed converter can be used for poly-phase Inductive Power Transfer (IPT) systems where generation of a rotating/travelling magnetic field is required.
