A Method for Enhancing Power Supply Stability Through Integrated Local Temperature Sensing and Control

In aerospace power systems, integrating temperature sensors and associated measurement circuits into local temperature control units usually requires additional space and complex design considerations. This not only increases the complexity of the system, but also imposes significant restrictions on equipment layout, especially in applications with strict volume and weight constraints. The temperature-sensitive, high-precision components in the power supply will drift due to the working environment temperature, resulting in a decrease in the accuracy of the power supply output, which places strict requirements on the performance of the local temperature control unit. These challenges highlight the urgent need for innovative solutions for aerospace power supplies. Therefore, this study proposes a novel temperature control method that uses diodes as temperature sensors and heat sources for temperature-sensitive, high-precision components in aerospace power supplies. By integrating the sensing and heating functions into a single diode, compensating for factors affecting the measurement accuracy and controlling the temperature of key high-precision components in the power supply, a stable voltage output can be achieved. This method solves the problem of installing multiple temperature sensors in the limited space of aerospace power supplies and reduces system complexity.
