Title
(EN) POWER CONVERTERS
(FR) CONVERTISSEURS DE PUISSANCE
Abstract
(EN) A power converter can include first, second, third, and fourth power switches, and a driver for operating the drive switches to modify an input voltage. An AC coupling capacitor can be coupled between the first and fourth power switches. Bootstrap capacitors can be used for driving the first and second power switches, which can be high-side switches. In some embodiments, a current sensing circuit can be used to measure current through the third and/or fourth power switches and for determining the current through the power converter. In some embodiments, the power converter can monitor the voltage across the AC coupling capacitor and can determine the current through the power converter based on the monitored voltages. In some embodiments, the AC coupling capacitor can be pre-charged before the power converter begins normal operation.
(FR) L'invention concerne un convertisseur de puissance qui peut comprendre des premier, deuxième, troisième et quatrième commutateurs de puissance et un circuit d'attaque pour faire fonctionner les commutateurs d'attaque pour modifier une tension d'entrée. Un condensateur de couplage CA peut être couplé entre les premier et quatrième commutateurs de puissance. Des condensateurs d'amorçage peuvent être utilisés pour commander les premier et deuxième commutateurs de puissance, qui peuvent être des commutateurs côté haut. Dans certains modes de réalisation, un circuit de détection de courant peut être utilisé pour mesurer le courant à travers les troisième et/ou quatrième commutateurs de puissance et pour déterminer le courant à travers le convertisseur de puissance. Dans certains modes de réalisation, le convertisseur de puissance peut surveiller la tension à travers le condensateur de couplage CA et peut déterminer le courant à travers le convertisseur de puissance sur la base des tensions surveillées. Dans certains modes de réalisation, le condensateur de couplage CA peut être préchargé avant que le convertisseur de puissance ne commence à fonctionner normalement.
