Loadamitic Self-adapting Drive for GTR
-
摘要: 本文分析了PWM放大器晶體管各階段的工作狀態,給出最佳基極驅動電流波形并提出了根據晶體管負載狀況自動調節基極驅動電流的動態負載自適應技壽,采用此項技壽設計的驅動電路已經幾年運行考核,解決了晶體管控制系統的關鍵難題.Abstract: The GTR staged work state of PWM amplifer is analysed. A optimum base driving current waveform is given out. And loadamitic self-adapting technique, which adjusts base driving current according to GTR load state, is advanced. Drive circuits being designed by the technoque has worked for years and won approval. The crux of GTR control system has been solved.
