Voltage Difference Adjustment Circuit for a Linear DC Stabilized Power Supply
This paper proposes a voltage difference adjustment circuit that can automatically adjust the input voltage in different stages while ensuring the working voltage drop of the adjustment tube,thereby improving the overall efficiency of the machine.The designed circuit consists of a multi winding power frequency transformer,winding switching circuit,voltage comparator circuit,and output voltage sampling circuit.Positive feedback is introduced into the voltage comparator circuit to make the circuit have hysteresis characteristics,further improving the reliability of winding switching.By adjusting the pres-sure difference,the power dissipation of the adjustment tube is effectively reduced,the system's requirements for heat dis-sipation units are reduced,and the cost-effectiveness of the power supply is improved.
