摘　　要：针对等离子体放电开关组件的小型化、集成化问题,介绍了一种采用新型的低温共烧铁氧体(LTCF)微磁变压器触发等离子体放电开关的技术,相对于传统触发技术,可大幅度减小降低体积,提高可靠性,实现集成化。现有单级升压方案采用高匝比变压器是集成的主要瓶颈和难点,多级升压方案所需的高压电源集成难度更大。基于LTCF微磁变压器触发等离子体放电开关,通过能量存储和释放过程实现低压到高压变换,避免采用高匝比变压器,且电路简单。电路试验表明,12~28 V输入电压均能产生出1500 V以上的电压,可靠的触发等离子体放电开关。To solve the problem of miniaturization and integration of plasma discharge switch components, a new technology of triggering plasma discharge switch with low-temperature cofired ferrite(LTCF) micromagnetic transformer is introduced. Compared with traditional triggering technology, it can greatly reduce the volume and improve reliability,achieving integration. The main bottleneck and difficulty in integrating the existing single-stage step-up scheme is the use of high turns ratio transformers, and the integration of high-voltage power supply required by the multi-stage step-up scheme is more difficult. Based on the LTCF micromagnetic transformer triggering plasma discharge switch, the low-voltage to high-voltage transformation is realized through the energy storage and release process, avoiding high turns ratio transformers and with a simple circuit. Circuit experiments show that voltages of over 1500 V can be generated with input voltages of 12 V to 28 V, reliably triggering the plasma discharge switch.
