“…Over the past decades, due to space limitations and issues related to weight and cost reduction, the evolution of power electronic systems tended toward systems with high energy density, leading to an efficiency increase [12][13][14][15]. High frequency Silicon switch circuits have unacceptable switching loss.…”

This paper proposes a new variable frequency zero voltage switching (ZVS) control method for boost converter operating in boundary conduction mode (BCM). The intended method keeps the converter in BCM despide of the load and input voltage variations. This is done by changing switching frequency in a certain specified range. The proposed method can guarantee circuit performance in BCM via zerocrossing detection of the inductor current and changing the switching frequency. In addition, with a slight modification in control structure, it is possible to achieve a fully ZVS in all cases. This converter control is carried out in analog form without using microprocessors which, compared with the digital one, has less noise, cost and processing challenges in high frequency applications. Simulation results obtained from applying the proposed method on a GaN-based synchronous boost converter in two different switching frequency ranges (100KHz and 1MHz) are indicative of the proposed strategy advantages.

“…The PFC stage assures a power factor close to the unity, a low harmonic distortion and generates a controllable DC voltage bus. This stage allows separating the mains front the multi-inverter structure, fulfilling EMC requirements [11][12][13][14][15][16] and making easier the control of the output power in the pot [17][18][19]. Besides, the bus voltage can be increased, decreasing the current through IH inverter and IH load, and, therefore, decreasing losses in these devices.…”

Flexible cooking surfaces, eg. fully active surfaces, have gained lately an increasing importance in the domestic induction heating. Multi-inverter structures are a cost-efficient solution to develop this technology. However, they add control restrictions that can be solved with a power factor corrector (PFC) stage as proposed in this work. The proposed converter and modulation strategy work with zero voltage switching (ZVS), decreasing the switching losses, enabling a higher working frequency and, therefore, decreasing the magnetic devices size. The bus voltage is controllable and can be increased, easing the load power control and decreasing current through load and inverter and, so, the power losses. Besides, the switching frequency is constant in the mains cycle and can be modified to synchronize the load inverter and the PFC stage avoiding intermodulation noise. A 3.6 kW prototype has been implemented fulfilling the EMC requirements. The experimental waveforms and efficiency have been measured to prove the feasibility of this proposal.
