摘要
针对高压转换系统存在的一些问题，设计了一种基于LT3757的地质雷达高频高压转换系统。主要从工作原理、电路结构和主元件的选择等方面给出了系统的设计过程。经过实验测试，该系统具有宽输入电压范围，可产生地质雷达所需的50V～500V稳定的输出电压，工作频率可达到1MHz。该系统体积小，可直接集成到地质雷达发射源电路上，功耗低，可有效提高电池野外工作时间。
Abstract
According to some questions of high-voltage converting system, a high-frequency and high-voltage converting system in geological radar based on LT3757 was designed. The design process was presented according to the operating principle, the circuit structure and the choice of main inverter. In the experiment, the system had the wide range of the input voltage, and could product a stability output voltage from 50V to 500V, which is geological radar need. The frequency can be up to l MHz. The system is so small that can be integrated into the circuit board of the GR transmitter. It has a high conversion efficiency that can effectively improve a battery field work time.
