Control of a resonant switching system with monitoring of the working current in an observation window |
摘要 |
Controlling a resonant switching system, which includes a first switch and a second switch in a half-bridge configuration for driving a resonant load. A corresponding control system includes command means for switching on and switching off the switches alternatively according to a working frequency of the switching system. The control system includes detection means for detecting a zeroing of a working current being supplied by the switching system to the resonant load in a temporal observation window; the observation window follows each switching off of at least one of the switches, and has a length equal to a fraction of a working period of the switching system. Correction means are then provided for modifying the working frequency in response to each detection of the zeroing in the observation window. |
