parafeed 中文意思是什麼
parafeed
解釋
並饋-
The " parafeed " ( parallel feed ) uses a large choke to provide the dc voltage to the anode
旁饋耦合使用一個大型的扼流圈來為屏級供給直流電壓。 -
Like the transformer coupled circuit, the choke feed in the parafeed circuit allows the output to swing above and below the power supply voltage
和變壓器耦合電路一樣，旁饋電路中地扼流圈也能容許輸出在高於和低於高壓的情況下波動。 -
In the parafeed circuit, the power supply ripple forms a voltage divider across the choke, and is not coupled to the output
在旁饋耦合中，電源漣波被扼流圈分壓，而不再耦合進輸出。 -
Five different structures are described : standard transformer coupling, parafeed, resistively loaded stage capacitively coupled to the output transformer, tube ( valve ) based constant current source load capacitively coupled to the output transformer, and solid state ( mos fet ) constant current source load capacitively coupled to the output transformer
我們將討論五種不同的方式：標準變壓器耦合；旁饋耦合；電阻性負載電容性耦合至輸出變壓器；膽恆流源負載電容性耦合至輸出變壓器；以及晶體管恆流源負載電容性耦合至輸出變壓器。 -
Advantages of this configuration : like parafeed, there is no dc in the transformer, so a smaller unit can be used
該結構的優點：和旁饋電路一樣，變壓器不需要通直流，所以可以做得比較小。 -
Disadvantages : like the resistor load example, much higher voltage is required. an extra tube is needed. lower efficiency than the parafeed or transformer example
缺點：和電阻負載一樣，高壓要求很高。需要增加膽管。比旁饋和變壓器負載效率更低。
