discrete pulses造句
例句與造句
- The simulation results are all in accordance with the theory analysis , some even better than the theoretical specification . the basic principle of discrete pulse frequency modulation on step - up dc / dc converter is testified , and this effort accumulates more experience to design
在完成電路原理分析與電路設計的基礎之上,應用eda軟件hspice對各個子電路模塊和整體電路進行了功能仿真及量化模擬,仿真結果均達到或優(yōu)于預定指標。 - The temperature range is - 30 ~ 80 . the topology of the step - up dc / dc converters and its basic principle is first analyzed in this thesis . then based on the conventional pfm control scheme , a discrete pulse frequency modulation is presented and the state space average model related to the ccm ( continue current mode ) and dcm is established
然后在傳統(tǒng)的脈沖頻率調制方式的基礎上,分析了一種離散脈沖頻率調制方式,并建立了這種調制方式下升壓型dc / dc變換器在電流連續(xù)( ccm )工作模式和電流斷續(xù)( dcm )工作模式的狀態(tài)空間平均模型。 - High - frequency link power converters are receiving increasing attention . when the input frequency of ac - ac converter is quite high , such as 20khz or above , in order to make sure the converter switching action is restricted to the zero crossing point of the link voltage , the switching cycle becomes discrete pulse spectrums , however , the conventional pwm converters are ruled out because they would fail either to the efficiency or the low - distortion criteria
當交-交變頻器的輸入頻率非常高，通常為20khz時，為了在零電壓條件下實現(xiàn)逆變器開關管的通斷，變換器的開關時刻必須選擇在高頻交流電壓脈沖為零時，這意味著變換器開關時刻在時間軸上成為不連續(xù)的點，而常規(guī)的硬開關pwm變換器是將開關時刻選擇在任意時刻。 - A circuit topology of the inverter with duty cycle extended active clamp forward style high frequency pulse dc link is adopted by each independent inverter . each inverter is cascaded by a circuit with duty cycle extended active clamp forward style high frequency pulse dc link and a dc / ac inverting bridge . the control strategy of voltage mode pwm forwardback is adopted by the former , and the control strategy of three - state discrete pulse modulation ( dpm ) hystersis current is adopted by the later
每個獨立的航空靜止變流器采用占空比擴展有源箝位正激式高頻脈沖直流環(huán)節(jié)電路拓撲，由占空比擴展有源箝位正激式高頻脈沖直流環(huán)節(jié)電路與dc ac逆變橋級聯(lián)而成，前級采用電壓型pwm前饋控制技術，后級采用三態(tài)dpm電流滯環(huán)控制技術。 - It's difficult to find discrete pulses in a sentence. 用discrete pulses造句挺難的
