The paper analyses the principle of variable frequency source and brings forward that using electric electron technology make variable frequency output , and using high power dynatron that is parallel connection magnify power 文中對該變頻電源的工作原理及主要硬件作了較詳細(xì)的介紹;提出利用電力電子器件實(shí)現(xiàn)輸出大功率。
In the circuit , using the way of step - by - step magnify , a normal sine wave signal through former circuit export for the next circuit , and this signal that have been magnified push the next step . the main magnify circuit use the method of high power dynatron that is parallel connection 在回路中采用逐級放大的方法,將一個標(biāo)準(zhǔn)的正弦波信號通過前級放大,輸出給后級,推動后級放大回路,主要的功率放大回路中采用大功率三極管并聯(lián)實(shí)現(xiàn)功率放大輸出。
Secondly , we make an in - depth study and analysis in allusion to the given oscillatory circuit - butler common base harmonic circuit . the detailed analysis of the dynatron which is the main noise source in the oscillatory circuit is also made , including how excitation affects the dynatron and crystal 然后針對特定的振蕩電路結(jié)構(gòu)-串聯(lián)型巴特勒共基振蕩電路-進(jìn)行深入的研究和分析,并對主振電路中主要的噪聲源-三極管進(jìn)行的深入分析,包括激勵對三極管及晶體的影響。
