“…In IPT system, a high frequency current is desired to drive the magnetic field coupler so that the magnetic flux can flow through it to provide the load with the required power. Therefore, a Class-E inverter is designed as the high frequency inverter [17,18] at the transmitter to convert DC source to AC. On the other hand, the problem of power loss during the transmission process is overcome by proposing LCCL impedance matching circuits at the receiver part.…”

Since many years ago, kitchen appliances are powered up by cable connected. This create a troublesome case as wire might tangle together and cause kitchen table messy. Due to this, wireless power technology (WPT) is introduced as its ability is to transmit power to load without physical contact. This leads to cordless solution better in safety as the product can be completely seal, highly expandable power range. This work focuses on the design of WPT based on inductive approach to power up multiple kitchen appliances. The selection of inductive approach over its partners capacitive and acoustic is mainly due to high power efficiency. Class E inverter is proposed here to convert the DC to AC current to drive the inductive link. A 1 MHz operating frequency is used. To ensure the circuit is robust with load variations, an LCCL impedance matching is proposed. This solution is table to maintain the output power if there is a slight change in load impedance. Finally, the developed prototype is able to supply 50V utput which can achieve power transmission up to 81.76%.

“…In Figure 14, the coupling capacitors C M1 and C M2 can provide isolation between the primary and secondary sides and also act as resonant components in the CPT system. The circuit working principle is similar to a regular class E converter under the control of switch S. It indicates that any resonant converter with series-connected capacitors can be used to realize a CPT system, for example, the class E converter can be combined with a LCCL resonant network to establish resonances in the circuit, and effective power transfer can be realized [45].…”

Capacitive power transfer (CPT) technology is an effective and important alternative to the conventional inductive power transfer (IPT). It utilizes high-frequency electric fields to transfer electric power, which has three distinguishing advantages: negligible eddy-current loss, relatively low cost and weight, and excellent misalignment performance. In recent years, the power level and efficiency of CPT systems has been significantly improved and has reached the power level suitable for electric vehicle charging applications. This paper reviews the latest developments in CPT technology, focusing on two key technologies: the compensation circuit topology and the capacitive coupler structure. The comparison with the IPT system and some critical issues in practical applications are also discussed. Based on these analyses, the future research direction can be developed and the applications of the CPT technology can be promoted.

“…The Class‐E LCCL that had been developed in [18] was extended by introducing a Boost converter and multiple coupling plates. At a glance, the modelling of Class‐E LCCL rotary CPT system can be represented by two cascaded blocks, namely Class‐E Δ1b and LC output‐matching network, as seen in Fig.…”

“…All circuit elements are assumed ideal. The circuit equations for this topology can be referred to [18, 20]. Begin with the output power, P o equation,

P_{o} = \frac{8 V_{DC}^{2}}{π^{2} + 4} (\frac{1}{R_{T}})

where R T is the total series resistance seen at terminal ab , as simplified in Fig.…”
