(EN) ACTIVE SWITCHING RECTIFIER EMPLOYING MOSFET AND CURRENT-BASED CONTROL USING A HALL-EFFECT SWITCH
(FR) REDRESSEUR À COMMUTATION ACTIVE EMPLOYANT UN MOSFET ET UNE COMMANDE À BASE DE COURANT UTILISANT UN COMMUTATEUR À EFFET HALL
Abstract
(EN)
An active switching rectifier circuit uses a MOSFET and applies a current based control to turn the MOSFET on and off. The MOSFET has its source and drain connected between an AC phase or neutral line and the DC output. A current detection and control circuit has an input current conductor coupled in series with the source-drain current of the MOSFET; it outputs a switching control signal based on the current in its input conductor and applies the signal to the gate of the MOSFET for on/off control. A Hall-effect switch may be used in the current detection and control circuit. The rectifier may also include a voltage supply circuit for supplying a DC voltage to the current detection and control circuit. The rectifier circuit can be adapted for various configurations including single-phase half-wave, center-tap dual-phase full- wave, single-phase full-wave, and three-phase full-wave.

L'invention concerne un circuit redresseur à commutation active qui utilise un MOSFET et applique une commande à base de courant pour rendre le MOSFET passant ou bloqué. La source et le drain du MOSFET sont connectés entre une ligne de phase ou de neutre en courant alternatif et la sortie en courant continu. Un circuit de détection et de commande de courant possède un conducteur de courant d'entrée branché en série avec le courant source-drain du MOSFET. Il délivre en sortie un signal de commande de commutation basé sur le courant dans son conducteur d'entrée et applique le signal à la gâchette du MOSFET pour la commande tout ou rien. Un commutateur à effet Hall peut être utilisé dans le circuit de détection et de commande de courant. Le redresseur peut également inclure un circuit d'alimentation en tension destiné à délivrer une tension continue au circuit de détection et de commande de courant. Le circuit redresseur peut être adapté pour diverses configurations, y compris la demie-alternance monophasée, la double alternance biphasée à prise centrale, la double alternance monophasée et la double alternance triphasée.
