Magnetic Resonance Sounding

On the basis of the principles and characteristics of the various switching power supply, we have designed a high-power supply which can be used for the magnetic resonance sounding equipment for detecting mine ground water. The characteristics of the switching power supply are the full-bridge converter as the main power topology and the SG3525 chip as the core of the control. The high frequency PWM signal generated by the SG3525 can drive the four power switch tubes of the full-bridge circuit to conduct alternately thought the IR2110, so we can get continuous and stable DC output voltage. The design of the switching power supply has a lot of advantages, such as high efficiency, low noise, high stability, and small volume weight.

Consumption Control

Aiming at reducing standby power consumption of switching power supply, a low standby power consumption control circuit for switching power supply is designed. The control circuit is composed of power switches, the driving circuit, the load detection circuit and the low power supply circuit. The control circuit effectively closed the input of switching power supply when the switching power supply is without load. The control circuit ensures the normal work of switching power supply when the switching power supply is with load. From the experiment results, the control circuit can effectively reduce standby power consumption of switching power supply.
