“…Choke coil feeds the resonance circuit with a regulated constant current and prevents instantaneous current pulses from flowing to resonance capacitor. This circuit type is preferred at higher power and frequencies compared to applications with series resonant inverter [7]. Induction heating system contains power electronics elements and active inductive circuit elements.…”

Today, with the increased energy needs, carbon emission caused by energy production affects the environment negatively. This situation has made it necessary that electrical energy should be used efficiently. In order to achieve this, institutions such as IEEE and IEC have established some electrical energy standards to be complied with, by the consumers. In order to increase energy efficiency following these standards, current and voltage harmonics in the system must be eliminated or kept at the required limit. Otherwise, these harmonics will cause deterioration of receivers fed from the distribution network or decrease in operating performance. For this reason, power factor correction (PFC) processes are applied in power systems. Induction heating systems, which have found a wide area of use in recent years, require PFC process due to their structure consisting power electronics elements and inductive heating crucible. This study aims to eliminate the network harmonics and harmonics distortions and to bring the power factor (PF) closer to '1' by using AC-DC converter with PFC in induction heating system. Induction heating system designed in the study has three phases and has a full bridge parallel resonance inverter operating at a frequency of 20 kHz and power of 17 kW. The system uses full wave uncontrolled rectifier and boost type DC-DC converter. Voltage control is provided through the PID controller. Designed system is simulated in MATLAB. Current and voltage graphics measured from network and load were evaluated, PF and THD values were analyzed.

In this paper, a novel non‐isolated bidirectional dc‐dc converter (NBDC) is proposed. Compared with other topologies proposed recently, the proposed converter has the advantages of high voltage gain, wide voltage range, and common ground, which is suitable for the application of electric vehicles (EVs). The operating principle, steady‐state analysis, performance comparison, and the small signal modeling of the proposed converter are presented in detail. Finally, a 265‐W prototype is built to verify the feasibility of the proposed converter. The experimental results well confirm the corresponding theoretical analysis, and the prototype has a peak efficiency of 92.81% and 93.61% in step‐up mode and step‐down mode, respectively.
