Title
(EN) SWITCH MODE POWER CONVERTER
(FR) CONVERTISSEUR DE PUISSANCE À DÉCOUPAGE
Abstract
(EN)
A switch mode power converter comprises an inverter, a transformer having a primary side winding and a secondary side winding and a first inductor in series with the primary side winding. A second inductor is provided magnetically coupled to the first inductor, and a voltage at one end of the second inductor is used as a feedback signal for indirectly measuring (i.e. approximating) the secondary side voltage, but with measurement at the primary side.
(FR)
La présente invention concerne un convertisseur de puissance à découpage comprenant un onduleur, un transformateur ayant un enroulement côté primaire et un enroulement côté secondaire et un premier inducteur en série avec l'enroulement côté primaire. Un deuxième inducteur est couplé magnétiquement au premier inducteur, et une tension à une extrémité du deuxième inducteur est utilisée comme signal de rétroaction pour mesurer indirectement (c'est-à-dire estimer) la tension côté secondaire, mais avec une mesure au niveau du côté primaire.
