大功率开关电源一般采用三相二极管整流桥作为前级整流电路。
The switching power supply usually uses the diodes rectifier as the front converter.
同时在二极管整流桥前用简单滤波电路抑制谐波造成谐波抑制不彻底。
At the same time, before the diode bridge rectifier it USES filter circuit with a simple harmonic suppression which can not fulfil the complete harmonic suppression.
具有发光二极管的一块印刷电路板和装在上面的一个二极管整流桥被容纳在一个凹座中。
A printed circuit board having light emitting diodes and a diode rectifier bridge mounted thereon is retained in a recess formed in the base portion of the light reflector.
