摘要

DC-DC变换器由PWM-IC(脉宽调制集成电路)控制器、MOSFET(金属氧化物半导体场效应晶体管)、电感、电容等组成。采用PWM控制和调节总输出电压。结果表明，MOSFET阈值电压的变化和辐射效应引起的偏置电压的增加使PWM脉冲不稳定。辐射是影响pwm集成电路和MOSFET电学特性变化的主要因素。利用集成电路重点(SPICE)仿真程序研究了PWM操作中缺失脉冲、脉宽变化和输出波形变化，并与实验结果进行了比较。

A study on radiation effects on PWM-IC controller of DC/DC power buck converter

DC-DC converter is composed of a PWM-IC (pulse width modulation-integrated circuit) controller, a MOSFET (metal-oxide semiconductor field effect transistor), inductor, capacitor, etc. PWM is applied to control and regulate the total output voltage. It is shown that the variation of threshold voltage at MOSFET and the offset voltage increase caused by radiation effects make the PWM pulse unstable. Radiation gives the main influence on the changes in the electrical characteristics of PWM-IC and MOSFET. In the PWM operation, the missing pulses, the changes in pulse width, and a change of the output waveform are studied by the simulation program with integrated circuit emphasis (SPICE) and compared with experiments.
