“…The capacitor is always used to compensate reactive power to improve the power factor. According to the connection of capacitor C and coil, it can form two basic types of inverter: series resonant voltage type inverter and parallel resonant inverter (current mode) [9]. The inverter power supply is different for different types of inverter.…”

A single-sided induction heating system based on IGBT is proposed. The system includes the series resonant circuit, control circuit, and auxiliary circuit. The main circuit includes rectifier, filter, inverter, and resonant circuit. A drive circuit is designed for IGBT combing some protection circuits. We have a simulation of the single-sided induction heating system in ANSYS. The simulation results are compared with the experimental results. The performance of the system is promising. And also we estimate the temperature distribution model by the least squares theory.

“…A cutoff frequency of 300 kHz, one octave above the upper limit, would be more appropriate. This cutoff frequency requires a leakage inductance of 530 nH, which can be accomplished by letting the single-layer primary winding on the power-line side protrude out of the transformer window [10], [11].…”

“…The voltage transfer function of this circuit (in the receiving direction) is expressed by (10) where represents the referred modem impedance. From (10), it is clear that the power-line impedance has no influence on the voltage transfer function in the receiving direction. The amplitude response of (10) was simulated and is shown in Fig.…”

In this paper, the design of an impedance-adapting bidirectional transformer coupling circuit for low-voltage powerline communications is described. It is shown that transmission through the transformer is governed by series resonance of the leakage inductance and coupling capacitance. At low frequencies though, the magnetizing inductance plays an important role in filtering the power waveform. The coupling transformer, if properly designed, can equalize terminating impedances on either side for maximum power transfer. Furthermore, these equalized terminating impedances facilitate symmetrical bidirectional band-pass transmission.

This paper introduces an improved zero-voltage and zero-current-switching half bridge (ZV-ZCS HB) DC/DC converter for medium and high-power applications. The soft switching is obtained by adding only small capacitors. The operation principle and design procedure are presented together with an analysis of the total losses in the switch. By using the proposed operation principle and design procedure zero-voltagezero-current switching and high efficiency operation for full load range are provided. The operation and design considerations are illustrated and verified on a 6-kW prototype, which has been simulated (PSPICE) and successfully tested at 20 kHz operating frequency. The obtained efficiency is above 97% for full load. Increasing the operating frequency above 50kHz is possible, which contributes to a decrease of the losses in the transformer and to a reduction the size and weight. The simple topology, high efficiency and low cost make the proposed converter attractive for medium and high power applications.
