Title
(EN) SYSTEM AND METHOD FOR PROVIDING BI-DIRECTIONAL POWER FLOW AND POWER CONDITIONING
(FR) SYSTÈME ET PROCÉDÉ POUR ASSURER UN FLUX D'ÉNERGIE BIDIRECTIONNEL ET UN CONDITIONNEMENT DE PUISSANCE
Abstract
(EN) A system and method for providing symmetric, efficient bi-directional power flow and power conditioning for high-voltage applications. Embodiments include a system that comprises a first normally-on junction field-effect transistor (JFET) having a drain that forms a first coupling node and a first normally-off semiconductor transistor having a drain coupled to a source of the first normally-on JFET and a source coupled to a gate of the first normally-on JFET, wherein a high voltage on the first coupling node provides a negative voltage on the gate of the first normally-on JFET resulting in blocking of the high voltage and mitigating power flow through the normally-on JFET and normally-off semiconductor transistor.
(FR) L'invention porte sur un système et un procédé pour assurer un flux d'énergie bidirectionnel efficace symétrique et un conditionnement de puissance pour des applications hautes tensions. Des modes de réalisation portent sur un système qui comprend un premier transistor à effet de champ à jonction (JFET) normalement passant comprenant un drain qui forme un premier nœud de couplage et un premier transistor à semi-conducteur normalement bloqué comprenant un drain couplé à une source du premier JFET normalement passant et une source couplée à une grille du premier JFET normalement passant, une tension élevée sur le premier nœud de couplage procurant une tension négative sur la grille du premier JFET normalement passant entraînant le blocage de la tension élevée et limitant le flux d'énergie à travers le JFET normalement passant et le transistor à semi-conducteur normalement bloqué.
