single-shift control
解釋
單切換控制-
A novel high - power pollution - free smps is presented in this paper, which accomplishes simultaneously the goal of soft - switching pwm, the input / output isolation, the output voltage regulation and three - phase pfc with a single - stage power processor and simple pseudo - phase - shift control circuit. therefore, compared with the normal two - stage system, the single - stage power supply has simpler structure, lower cost, higher efficiency and easier to control. the proposed smps can be used in the three - phase power system, and can output high power over kw - order and input / output ( i / o ) isolation dc power supply
本文提出的新型無污染大功率開關電源正是採用三相三線制輸入電源，利用單級偽相移零電壓零電流開關脈寬調制（ pps - zvzcs - pwm ）全橋變換器完，成功率因數校正（ pfc ）和輸出電壓快速調節、隔離的雙重功能，並且該變換器開關管在零電壓或零電流下通斷，顯著的減小了emi 。 -
The load - control apparatus adopted a single - chip microcomputer system, whose mcu was a kind of high - speed processor - ds80c320, whose a / d switched apparatus was max180, whose low - pass filter was max293, whose f / v transformed circuit was lm331, whose controlled silicon phase - shift touch - off circuit was tca785, and whose communicating interface of rs232 was max202. the watchdog of the mcu was max705 and the system used an on - off electrical source to supply power
球磨機負荷控制儀採用了單片機系統， mcu採用ds80c320高速處理器，採用max180作為md轉換器，低通濾波器為max293 ， f v轉換電路利用lm331 ，可控硅移相觸發電路使用tca785 ， rs232通信介面晶元採用max202 ， mcu監控電路為max705 ，系統使用開關電源供電。
