Title
(EN) A METHOD AND SYSTEM FOR ALTERNATING CURRENT REGULATION
(FR) PROCEDE ET SYSTEME DE REGULATION DE COURANT ALTERNATIF
Abstract
(EN)
Circuitry and methods for regulating alternating current regulation uses energy storage and release principles to boost or buck voltage to permit regulated ac operation with parallel and series bi-directional switch elements (12) and (13) operated at either variable duty cycles or frequencies to accommodate bipolar ac operation. Each bi-directional switch element may include a diode bridge (8) or (10) and directionally limited switches such as semiconductor switches. The system can be used to regulate ac even during sub-cycle dips, can be used to simulate controlled dips, can be used to correct power factor for loads, and can be applied in multiphase operations.

La présente invention concerne des circuits et des procédés destinés à la régulation de courant alternatif (CA) utilisant des principes de stockage d'énergie et de dégagement d'énergie afin d'augmenter ou de diminuer une tension dans le but d'obtenir un fonctionnement de CA, régulé à l'aide d'éléments (12) et (13) de commutation bidirectionnels en série et en parallèle fonctionnant à fréquences ou à facteurs d'utilisation variables de manière à permettre un fonctionnement bipolaire de CA. Chaque élément de commutation bidirectionnel peut comprendre un pont diode (8) ou (10) et des commutateurs limités en direction tels que des commutateurs semi-conducteurs. Le système peut être utilisé afin de réguler du CA même durant des creux de tension en sous-cycle, de simuler des creux de tension contrôlés, de corriger un facteur de puissance pour des charges, et dans des opérations multiphases.
