parafeed meaning in English
并馈
Examples
- The " parafeed " ( parallel feed ) uses a large choke to provide the dc voltage to the anode
旁馈耦合使用一个大型的扼流圈来为屏级供给直流电压。 - In the parafeed circuit , the power supply ripple forms a voltage divider across the choke , and is not coupled to the output
在旁馈耦合中,电源涟波被扼流圈分压,而不再耦合进输出。 - Advantages of this configuration : like parafeed , there is no dc in the transformer , so a smaller unit can be used
该结构的优点:和旁馈电路一样,变压器不需要通直流,所以可以做得比较小。 - Like the transformer coupled circuit , the choke feed in the parafeed circuit allows the output to swing above and below the power supply voltage
和变压器耦合电路一样,旁馈电路中地扼流圈也能容许输出在高于和低于高压的情况下波动。 - Disadvantages : like the resistor load example , much higher voltage is required . an extra tube is needed . lower efficiency than the parafeed or transformer example
缺点:和电阻负载一样,高压要求很高。需要增加胆管。比旁馈和变压器负载效率更低。
