A power supply for inductively powering a remote device has an inverter operating at an operating frequency and a primary coil, A phase comparator compares the phase of the voltage or current delivered by the power supply. If the phase relationship detected by the comparator is unacceptable, the inverter is disabled. After a period of time, the inverter is re-enabled, and the phase relationship is again determined.
L'invention concerne un bloc d'alimentation permettant d'alimenter par induction un dispositif distant. Ce bloc d'alimentation comprend un convertisseur continu-alternatif fonctionnant à une fréquence de fonctionnement et un enroulement primaire. Un comparateur de phase compare la phase de la tension ou du courant délivré par le bloc d'alimentation. Si la relation de phase détectée par le comparateur n'est pas acceptable, le convertisseur continu-alternatif est désactivé. Après une période, le convertisseur continu-alternatif est réactivé et la relation de phase est à nouveau déterminée.
