Abstract:
(EN) A rectifying circuit and a direct current/direct current (DC/DC) converter. The rectifying circuit, applied to the DC/DC converter, comprises a transformer (101), a switch tube (102), a capacitor (103) and a load impedance (104). The positive electrode of a secondary coil of the transformer is connected to the positive electrode of the load impedance and the positive electrode of the capacitor; the negative electrode of the secondary coil of the transformer is connected to the drain electrode of the switch tube; the source electrode of the switch tube is connected to a metal shell (105) of the DC/DC converter; the metal shell of the DC/DC converter is connected to the negative electrode of the load impedance and the negative electrode of the capacitor; and the gate electrode of the switch tube accesses a pulse width modulated (PWM) signal. The rectifying circuit may reduce the volume of the DC/DC converter and reduce line loss.
(FR) L'invention concerne un circuit de redressement et un convertisseur courant continu/courant continu (CC/CC). Le circuit de redressement, appliqué au convertisseur CC/CC, comprend un transformateur (101), un tube de commutation (102), un condensateur (103) et une impédance de charge (104). L'électrode positive d'une bobine secondaire du transformateur est reliée à l'électrode positive de l'impédance de charge et à l'électrode positive du condensateur ; l'électrode négative de la bobine secondaire du transformateur est reliée à l'électrode de drain du tube de commutation ; l'électrode de source du tube de commutation est reliée à une coque métallique (105) du convertisseur CC/CC ; la coque métallique du convertisseur CC/CC est reliée à l'électrode négative de l'impédance de charge et à l'électrode négative du condensateur ; et l'électrode de grille du tube de commutation accède à un signal à modulation d'impulsions en durée (PWM). Le circuit de redressement permet de réduire le volume du convertisseur CC/CC et de réduire la perte de ligne.
(ZH) 一种整流电路以及直流-直流变换器,整流电路应用于直流-直流DC/DC变换器,整流电路包括变压器(101)、开关管(102)、电容(103)和负载阻抗(104),变压器的次级线圈的正极连接负载阻抗的正极和电容的正极;变压器的次级线圈的负极连接开关管的漏极;开关管的源极连接DC/DC变换器的金属外壳(105);DC/DC变换器的金属外壳连接负载阻抗的负极和电容的负极;开关管的栅极接入脉冲宽度调制PWM信号。该整流电路可以减少直流-直流变换器的体积,降低线路损耗。
