摘　　要：从电流变(ER)高压电源的微型化与智能化要求出发,对电流变型高压电源进行了设计.为满足微型化要求,选用了新型的压电陶瓷变压器作为系统的升压元件,并设计了单端工作方式的驱动电路;利用以SG3524为核心的PWM技术来提高电源系统的调节响应速度;运用以80C196KC为核心的单片机技术获得整个系统的智能控制性能.基于此,电源装置的体积及系统的响应控制程度都符合电流变器件的需要.For the requirements of the miniature and intelligence demand, an ER source is designed. In order to meet the miniature demand, the piezoelectric ceramic transformer is selected as the step-up component, and the drive circuit is adopted the driving way to the single-end. To promote the intelligent degree of the high-voltage source, the system uses the PWM technology relying mainly on SG3524 and the microcontroller technology taking 80C196KC as the core. Based on these, the volume of ER source and system response rate are in line with the needs of ER devices.
