This paper proposes the modulation scheme for grid connected full bridge inverter of single phase configuration to achieve ZVS condition with auxiliary switch. The THI PWM strategy is employed to control the auxiliary switch which is evolved from ZVS THI PWM, the DF modulation scheme is incorporated to generate auxiliary switching pulse. The ZVS THI PWM scheme is employed simultaneously on grid connected full bridge inverter and its performance is observed. The ZVS condition of inverter switches is also achieved by short circuit pulses generated from auxiliary switching pulses. The proposed control scheme with THI PWM and DF modulation scheme is modeled, the performance of full-bridge inverter of single phase configuration with control scheme is analyzed using MATLAB. The results depict that the proposed converter control scheme exhibits better performance compared to DF SPWM.

“…However, it is difficult to achieve these goals in a specific circuit, and additional knowledge and advanced technology are needed to overcome difficulties. In hard-switching technology, topology can mitigate high switching losses, improve the conversion efficiency and reduce the electromagnetic interference intensity while avoiding capacitive opening, inductive shutdown and diode reverse recovery (Feng et al, 2013) (Hu et al, 2014).…”

Purpose This paper aims to present an 8 kW LLC resonant converter designed for plasma power supply with higher efficiency and lighter structure. It presents how to solve the problems of large volume and weight, low performance and low efficiency of traditional plasma power supply. Design/methodology/approach At present, conventional silicon (Si) power devices’ switching performance is close to the theoretical limit determined by its material properties; the next-generation silicon carbide (SiC) power devices with outstanding advantages can be used to optimal design. This 8 kW LLC resonant converter prototype with silicon carbide (SiC) power devices with a modulated switching frequency ranges from 100 to 400 kHz. Findings The experimental results show that the topology, switching loss, rectifier loss, transformer loss and drive circuit of the full-bridge LLC silicon carbide (SiC) plasma power supply can be optimized. Research limitations/implications Due to the selected research object (plasma power supply), this study may have limited universality. The authors encourage the study of high frequency resonant converters for other applications such as argon arc welding. Practical implications This study provides a practical application for users to improve the quality of plasma welding. Originality/value The experimental results show that the full-bridge LLC silicon carbide (SiC) plasma power supply is preferred in operation under conditions of high frequency and high voltage. And its efficiency can reach 98%, making it lighter, more compact and more efficient than previous designs.
