| 摘 要： | 对于高频大功率电法勘探发送机而言,最脆弱的部位——逆变器容易烧毁,究其原因,主要是因为其本身的性能不高以及保护不力。针对目前存在的这些问题,提出了一种新的逆变器系统设计。在选用新一代功率器件IPM的基础上,采用适当的外围驱动和保护电路,通过设定恰当的死区时间,避免由于器件关断时间影响而导致的短路问题,并且通过单片机控制来实现多种死区时间可调,可以适应不同的发送频率和供电极距。

| Abstract: | Inverter, the weakest part of a high frequency and high power transmitter for electrical exploration, is liable to be destroyed. The reason is that the performance of the inverter is not good enough and the inverter protection is not satisfactory. Aiming at solving these problems, this paper presents a new inverter system which bases itself on a new power module-IPM and adopts right driver circuit and buffer circuit. It fits different transmitting frequencies and polar distances with proper settings of dead time, which is adjustable under the control of a micro controIler. |
