| 中文摘要 | 一種外形為2公分乘4公分乘5公分之無線交流電插頭,一組標準之直流輸出插座,及用以控制輸出電壓的8段式指撥開關,另一滑動式可變電阻,提供線性輸出電壓之選擇。內含電路,為一無變壓器直接交流轉直流(非磁力線耦合),由串接之2電容,以電力線密度耦合至大電容,其間以整流二極體,飛輪二極體,以提供持續直流的能力。另以電流源並接,以洩放超量的電荷。同時以電晶體串接穩壓,提供穩定的直流輸出電壓。由於穩壓由稽納二極體緩衝輸出,今將崩潰電壓不同之稽納二極體,置於指撥開關處,便可得到不同之穩定直流電壓,再者將最後之指撥開關與可變電阻連接,可達線性控制出電壓之能力。(所示之位置)代表數位操作,指撥開關s8導通,輸出為6V。 |
| 英文摘要 | An appearance like a wireless AC power plug , size of 5 cm cross 4cm , with a standard DC power outlet ,an 8 pin DIP SW to control DC output voltage ,another variable resistor on panel allowing linear DC output option. Inside box is the circuit to convert from AC to DC without transformer ( not magnetic flux coupling) ,using 2 serial capacitors ( C1,C2) and a rectifier diode (D2) in between ,to convert electricity flux from smaller capacitor to larger one , moreover with a free wheeling diode (D1) to the ground to get sustained DC current output .On the other hand paralleling a current source to deflate possibly overcharging. Meanwhile a Darlington transistor (Q1,Q3) in series output path to regulate stable output DC voltage. For buffered Zener diode could get regulated output voltage , different kind of breakdown voltage Zener diodes those gated by DIP switch , so the capability of different stable output voltages become reality .If a variable resistor in series the last DIP switch (s8) , the capability of linearly controlling the output voltage also achieved . |
