Synthesis of a High Step-up Bipolar Voltage Multiplier Using Level Shift Drivers

Abstract— In non-thermal food processing by utilizing an underwater shockwave, high voltage multiplier is required to generate an underwater shockwave. The conventional high voltage multipliers can generate a high voltage in a simple circuit configuration. However, the operation speeds of the conventional voltage multipliers are slow. Therefore, a novel high voltage multiplier for non-thermal food processing is proposed in this paper. Unlike the conventional multipliers, the proposed voltage multiplier is controlled by high speed four phase pulses generated by a level shift drivers which have bipolar input terminals. Therefore, the proposed voltage multiplier can generate a high voltage at high speed. Furthermore, the proposed voltage multiplier can achieve the smaller number of the circuit components than that of the conventional voltage multiplier. To confirm the validity of the proposed multiplier, experiments are performed concerning the proposed multiplier assembled with commercially available components.
