A 3kw single - phase half - bridge prototype circuit has been built with resonant frequency over 400 khz and excellent output performance 完成了3kw單相半橋試驗(yàn)電路,其諧振頻率高于400khz ,輸出效果很好。
A 6kw svm - based hysteresis current controlled three - phase full - bridge prototype circuit with the proposed controller has been built , and experimental results are also shown 在完成的6kw電流滯環(huán)控制空間矢量調(diào)制( hcc - svm )的三相全橋逆變器中驗(yàn)證了其效果,給出了試驗(yàn)結(jié)果。
A numerical analysis method is introduced to guide the low loss design for the inverter system , according which lead to a satisfied experiment results for a 3kw prototype circuit 同時(shí)對(duì)該方案進(jìn)行了損耗分析,提出了系統(tǒng)的損耗最小化設(shè)計(jì)方案,按照提出的控制和優(yōu)化方案設(shè)計(jì)了3kw系統(tǒng),給出了仿真和實(shí)驗(yàn)結(jié)果。
In addition , the paper presents filter multi - phase structure for the shaping - filter design and its fpga implementation , where multipliers can be omitted by using the look - up table of the filter coefficients rom . test of the prototype circuit board shows the method is perfect 然后介紹了數(shù)字成形濾波器多相結(jié)構(gòu)的fpga實(shí)現(xiàn)方法,運(yùn)用查詢系數(shù)rom的方法可以省去實(shí)現(xiàn)濾波器的乘法器結(jié)構(gòu),并對(duì)此實(shí)現(xiàn)方法進(jìn)行軟件仿真和硬件電路板測(cè)試,測(cè)試結(jié)果達(dá)到了較理想的效果。
