A High-Speed Bipolar Hybrid Cockcroft–Walton/Dickson Multiplier for Shockwave Non-thermal Food Processing

Abstract

For the design of shockwave non-thermal food processing systems, a novel high-speed bipolar voltage multiplier is presented in this paper. Unlike conventional high voltage multipliers, the proposed voltage multiplier has bipolar topology employing hybrid Cockcroft-Walton/Dickson multipliers (HCWDMs), where the bipolar HCWDM is driven by a driver circuit generating high speed rectangular pulses. Therefore, the proposed multiplier can achieve high speed operation. Through simulation program with integrated circuit emphasis (SPICE) simulations and experiments, the validity of the proposed multiplier is confirmed. The SPICE simulations and experiments reveal that the proposed multiplier outperforms the conventional HCWDM.
