<blockquote id="yfhku"></blockquote> 反激式開關電源變壓器設計的詳細步驟85W反激變壓器設計的詳細步驟 1. 確定電源規格. 1).輸入電壓范圍Vin=90—265Vac; 2).輸出電壓/負載電流:Vout1=42V/2A, Pout=84W 3).轉換的效率=0.80 Pin=84/0.8=105W 2. 工作頻率，匝比, 最低輸入電壓和最大占空比確定. Ｖmos*0.8>Vinmax+n(Vo+Vf)600*0.8>373+n(42+1)得n<2.5Vd*0.8>Vinmax/n+Vo400*0.8>373/n+42得n>1.34 所以n取1.6最低輸入電壓Vinmin=√[(Vacmin√2)* (Vacmin√2)-2Pin(T/2-tc)/Cin=(90√2*90√2-2*105*(20/2-3)/0.00015=80V取:工作頻率fosc=60KHz, 最大占空比Dmax=n(Vo+Vf)/[n(Vo+Vf)+Vinmin]= 1.6(42+1)/[1.6(42+1)+80]=0.45 Ton(max)=1/f*Dmax=0.45/60000=7.5us 3. 變壓器初級峰值電流的計算. Iin-avg=1/3Pin/Vinmin=1/3*105/80=0.4AΔIp1=2Iin-avg/D=2*0.4/0.45=1.78AIpk1=Pout/?/Vinmin*D+ΔIp1=84/0.8/80/0.45=2.79A 4. 變壓器初級電感量的計算. 由式子Vdc=Lp*dip/dt,得: Lp= Vinmin*Ton(max)/ΔIp1 =80*0.0000075/1.78 =337uH 取Lp=337 uH 5.變壓器鐵芯的選擇. 根據式子Aw*Ae=Pt*1000000/[2*ko*kc*fosc*Bm*j*?],其中: Pt(標稱輸出功率)= Pout=84W Ko(窗口的銅填充系數)=0.4 Kc(磁芯填充系數)=1(對于鐵氧體), 變壓器磁通密度Bm=1500Gs j(電流密度): j=4A/mm2;Aw*Ae=84*1000000/[2*0.4*1*60*103*1500Gs*4*0.80]=0.7cm4 考慮到繞線空間,選擇窗口面積大的磁芯,查表: ER40/45鐵氧體磁芯的有效截面積Ae=1.51cm2 ER40/45的功率容量乘積為 Ap = 3.7cm4 >0.7cm4 故選擇ER40/45鐵氧體磁芯. 6.變壓器初級匝數 1).由Np=Vinmin*Ton/[Ae*Bm],得: Np=80*7.5*10n-6/[1.52*10n-4*0.15] =26.31 取 Np =27T 7. 變壓器次級匝數的計算. Ns1(42v)=Np/n=27/1.6=16.875 取Ns1 = 17T Ns2(15v)=(15+1)* Ns1/(42+1)=6.3T 取Ns2 = 7T

隨著電磁閥在工業和日常應用的增多,其功耗越來越被人們所重視。通過對電磁閥驅動電路的研究,設計一套電磁閥節能驅動電路。不僅提高了電磁閥的響應時間,更重要的是降低了功耗,使電磁閥由工作在大電流狀態下,變成大電流啟動小電流維持的工作狀態。減少了由電流過大引起的電磁閥線圈過熱,增加了電磁閥的安全性。The power consumption of an electromagnetic valve is drawing increasingly more attentiori as it is widely used in industrial production and daily life. In this study, an energy - saving driving circuit of electromagnetic valves was designed. It can make an electromagnetic valve to start with a high current while work with a low current; thereby the power consumption can be reduced. Besides, it can shorten the response time of an electromagnetic valve and improve the security of the valve.

The GL823K integrates a high speed 8051 microprocessor and a high efficiency hardware engine for the best data transfer performance between USB and flash card interfaces. Its pin assignment design fits to card sockets to provide easier PCB layout. Inside the chip, it integrates 5V to 3.3V regulator, 3.3V to 1.8V regulator and power MOSFETs and it enables the function of on-chip clock source (OCCS) which means no external 12MHz XTAL is needed and that effectively reduces the total BOM cost.

Allegro導出 Gerber文件和鉆孔數據文件很多PCB廠家都沒有裝Allegro軟件，所以你不能直接發.brd文件。（很多PCB小廠連ProtelDXP也沒有，只支持Protel99）什么是Gerber文件Gerber文件是所有電路設計軟件都可以產生的文件，在電子組裝行業又稱為模版文件（stencil data），在PCB制造業又稱為光繪文件。可以說Gerber文件是電子組裝業中最通用最廣泛的文件格式Gerber文件是EIA的標準格式，分RS274-D和RS274-X兩種，其中RS274-X是RS274-D的擴展文件。生產制造部門在條件許可的情況下，應當盡可能要求用戶或設計部門提供RS274-X的Gerber文件，這樣有利于各工序的生產準備。準備工作為了保證出片的正確性，需要在設計PCB文件之前對一些系統參數進行設置，該設置包括畫圖的精度，圖片的尺寸，動態鋪銅的格式。設置畫圖的精度。在allegro中打開Setup->Drawing Size菜單，調出設置對話框，如圖1在對話框中確定User Units選擇Mils，Size選擇C，這樣整個作圖區域會大一點，相應的作圖范圍（Drawing Extents）變為Width：22000.00：Height：17000.00Left X和LeftY為原點坐標。Accuracy選擇2，其他根據你的尺寸自行定義。設置完成選擇OK按鈕，使配置生效。
