Abstract. For the efficiency problem of contactless charging in type of electromagnetic induction, this paper establishes a mathematical model of contactless charging in type of electromagnetic induction and the theoretical derivation. This contactless charging simulation model is founded by Matlab/Simulink, which uses the frequency of PWM generator, the mutual inductance value of the coil and load resistance of RL to simulate some conditions, such as the working frequency in practical work, the distance of coil, whether the coils are directed at the central, and changing of loads. Then through the influence of the changing frequency, load and mutual inductance, contactless charging in type of electromagnetic induction is analyzed. By the whole simulation experiment on contactless charging, the theory deduced from the mathematical model is verified, and the method to improve inductive contactless charging is proved.

“…To verify the effectiveness of the proposed structure and parameter design method, an SWTPI system with coupling position II, which was chosen in previous works [17][18][19][20][21][22][23], was built for comparison. The voltages on the main transmitting coil and transformer coil at the power transmission frequency ω p are listed in Table 2 and are based on the experimental data.…”

“…Position II was chosen in a previous work [17][18][19][20][21][22][23]. When Z3 is an open circuit (i.e., when the resonant compensation network is compensated by series resonance), the crosstalk at the two coupling positions is consistent.…”

“…C s1par , L s1par , L s2par and C spar can be neglected because these parasitic parameters are sufficiently small at the frequency that satisfies the limitation of (7). Thus, the relationship among the impedances of L s1 , C s1 , C s2 , and L s at the communication frequency and the power frequency is as follows: (22) According to the LCC structure described in Section 2.2, we obtain:…”

Abstract:The effective simultaneous wireless transmission of power and information (SWTPI) is an issue of great interest. To reduce the crosstalk between power and information channels while increasing the transmission air gap and power level, we introduce an inductor-capacitor-capacitor (LCC) compensation network for an SWTPI system. First, the crosstalk between the power and information channels is analyzed. An effective parametric design method is then proposed for the LCC compensation network, which is analyzed theoretically to minimize the crosstalk. Finally, experiments are conducted at 1000 W and 115.2 kbps with an air gap of 100 cm to verify whether the proposed structure and design method of the LCC compensation network are suitable for the SWTPI.

“…The contactless energy transfer systems have been recently gaining popularity and investigated widely [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. This innovative technology creates new possibilities to supply mobile devices with electrical energy because elimination of cables, and/or slip-rings as well as plugs and sockets increases reliability and maintenance-free operation of such critical systems as in aerospace, biomedical, electric vehicles and robotics applications.…”

Abstract.A novel Inductive Contactless Energy Transfer (ICET) system is presented in this paper. The energy is transferred using a rotatable air gap transformer and a power electronic converter. To minimize total losses of the system a series resonant circuit is applied, assuring zero current switching condition for IGBT power transistors. The analytical expression of the transfer dc voltage gain is given and discussed. The developed ICET system is characterized by high efficiency and fast FPGA based controller and protection system. The resonant frequency is adjusted by extreme regulator which follows instantaneous value of primary peak current. Simulated and experimental results which verify and illustrate operation of developed 3 kW laboratory model are presented.
