Abstract

Intense field dielectrics (IFD) are widely used in the air purification industry. DC power supplies must be designed to provide a high voltage for IFD products. Therefore, this paper introduces a compact 10 kV high-voltage DC power supply tailored for IFD air purification. It employees a novel controller, which is a fusion of a fixed-frequency PWM-based slidingmode controller and a phase-shift full-bridge configuration. The superiority of the proposed DC power supply topology is demonstrated. Rigorous simulation analysis employing MATLAB/Simulink shows that the robustness and stability of the new controller are much better than fixed-frequency PWM-based sliding-mode controllers. Subsequently, a high-voltage DC power prototype is fabricated, followed by comprehensive experimental validation. Test results underscore the stability of the DC power supply under normal operating conditions. Notably, when the controller adopts a linear PI configuration, the DC voltage output ripple is contained within a stringent threshold of ≤ 0.4%. Moreover, in the presence of AC power system oscillations, the novel controller showcases its ability to achieve a heightened response speed, which contributes to the robustness of the DC power supply.
