二极管整流 meaning in English
diode rectification
Examples
- The models of diode rectifier system and filter circuit , are established by using power system blockset ( psb ) , which are also supplied by matlab
利用matlab提供的电气系统模块( psb ) ，建立了二极管整流桥、滤波电路等元件的仿真模型。 - The second reason is the nonlinear rectifier with a bulky capacitor in the input stage of the smps , which leads to a narrow pulse and rich harmonics
原因之二是开关电源的输入端采用二极管整流，后接较大的滤波电容，导致输入电流为一很窄的脉冲波，含有丰富的谐波分量。 - The input of traditional ac - dc converter is diode - capacitance combined circuit . it ? input current wave presents pulse shape , and the power factor ( pf ) on ac line side is low
传统的ac ? dc开关变换器输入端是二极管整流-滤波电容组合电路，其输入电流波形呈脉冲状，交流网侧功率因数很低。 - It could be a battery source ; however , in most case , the input is a diode rectified ac line voltage with a large filter capacitance , to provide a low internal impedance and low - ripple dc voltage source
该直流电压源可能是一个电池，然而在大多数的情形是一个经二极管整流的交流电压再加上一个大的滤波电容，用以提供一个低内阻、低脉动的直流电压。 - Not only do thyristor - rectifiers produce harmonic current to electric networks , but also their factor is lower when deeply controlled . although diode - rectifiers can improve the power factor , they can still input harmonic to electric networks . besides , the voltage on dc bar ca n ' t be controlled for diode - rectifiers . the appearance of pwm rectifier offers a new way to solve the problem from the traditional rectifiers
相控整流不但会产生谐波电流污染电网，而且其深控时功率因数会降低；尽管二极管整流能改善网侧功率因数，但仍会产生谐波电流污染电网，同时其直流电压的不可控性也是一个大的缺点。
