Design of a high-frequency and high-voltage converting system in geological radar based on LT3757
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.
