In this paper, a high-voltage driver with a switch-capacitor cell and a current-sensing resistor for implementing the functions of zero-voltage switching (ZVS) and overcurrent protection is proposed. It has the following advantages: (1) By using a switch-capacitor cell for implementing the function of ZVS, we can reduce the switching losses of active switches. (2) By using a voltage-doubler circuit, we can easily obtain a high voltage (8 kV). (3) By incorporating a sensing resistor and a logic circuit, we can sense overcurrent conditions to achieve the function of protection. Therefore, the proposed high-voltage driver can increase efficiency and safety. To verify its performance, a prototype of the proposed high-voltage driver is built. The experimental results have confirmed that the proposed high-voltage driver with a switch-capacitor cell and a current-sensing resistor for implementing the functions of ZVS and overcurrent protection is suitable for application to air cleaners.
