1. Transfòmatè pouvwa
Pouvwa transfòmatè se yon kalite eleman mou mayetik elektwomayetik, ki gen fonksyon se transmisyon pouvwa, konvèsyon vòltaj ak izolasyon izolasyon, epi li lajman ki itilize nan teknoloji ekipman pou pouvwa ak teknoloji elektwonik pouvwa.
2. sikwi redresman
A "rectifier circuit" (recTIfying circuit) is a circuit that converts alternating current electrical energy into direct current electrical energy. Most rectifier circuits are composed of transformers, rectifier main circuits and filters. It is widely used in DC motor speed regulation, generator excitation regulation, electrolysis, electroplating and other fields. The rectifier circuit usually consists of the main circuit, filter and transformer. After the 1970s, the main circuit is mostly composed of silicon rectifier diodes and thyristors. The filter is connected between the main circuit and the load to filter out the AC components in the pulsating DC voltage. The transformer setting depends on the specific situation. The function of the transformer is to achieve the matching between the AC input voltage and the DC output voltage and the electrical isolation between the AC grid and the rectifier circuit.
Fonksyon sikwi redresman an se konvèti kouran altènatif ak pwodiksyon vòltaj ki pi ba pa sikwi etap-desann AC nan yon sèl-fason pulsasyon aktyèl dirèk, ki se pwosesis redresman aktyèl la altène. Kous redresman an se sitou ki konpoze de dyod redresman. Vòltaj la apre yo fin ale nan kous la redresman se pa vòltaj AC ankò, men yon vòltaj melanje ki gen vòltaj DC ak vòltaj AC. Li se nòmalman rele unidirectionnel pulsation DC vòltaj.
3. Filtre kous
Se sikwi a filtre souvan itilize filtre rid la nan vòltaj pwodiksyon an rektifye, epi li jeneralman konpoze de eleman reyaktif, tankou yon kondansateur C nan paralèl ak rezistans nan chaj, oswa yon induktè L nan seri ak chaj la, ak konplèks divès kalite konpoze. nan kondansateur ak induktè. sikwi filtre.
4. sikwi regilatè
Yon sikwi regilatè vòltaj refere a yon kous ki ka kenbe vòltaj pwodiksyon an konstan lè vòltaj la opinyon, chaj, tanperati anbyen, paramèt sikwi, elatriye chanje. Sikwi sa a ka bay pouvwa DC ki estab epi li lajman ki itilize nan divès kalite ekipman elektwonik.
