摘要

摘要: 线性电源因其干扰小、动态响应速度快等优点被广泛用作半导体激光器驱动电源。针对线性电源中调整管易因功耗过大发生故障的问题，提出了一种脉宽脉幅混合调制方法，利用调整管漏源电压和漏极电流调制生成高频方波，通过平均值电路计算方波平均值，并基于此方法设计了一种调整管功耗检测电路。搭建实验平台对电路进行测试，结果表明，电路检测精度高、硬件成本低、响应速度快，最大检测误差为−2.64%，线性拟合度为0.9987，可广泛用于调整管的功耗检测以及安全区保护。

Abstract: Linear power supply is widely used as the driving power of semiconductor laser because of its advantages such as low interference and fast dynamic response. To solve the problem that the regulating tube fails due to excessive power consumption, this paper proposes a hybrid pulse width-pulse amplitude modulation strategy, which uses the drain-source voltage and drain-current of the regulating tube to modulate high frequency square wave, and calculate the mean value of square wave, based on which the regulating tube power consumption detection circuit is designed. An experimental platform is built to test the circuit, and the results show that the circuit has the advantages of excellent detection accuracy, low hardware cost and fast response. The circuit has a maximum relative error of $- 2.64{\text{%}}$ and a linearity fit of $0.9987$ . It can be widely used for power consumption measurement and safety zone protection of regulating tube.
