Abstract: The present disclosure discloses a method and device for forming a groove on an electrode plate. The method for forming a groove on an electrode plate includes: thinning an active material layer by a laser method, where the active material layer is located in a to-be-grooved area of the electrode plate; and removing the thinned active material layer by a physical removal method to form an accommodating groove that exposes the current collector layer. By adopting a combination of the laser method and the physical removal method, the present disclosure, the present disclosure, on the one hand, can quickly remove the active material layer in the to-be-grooved area, and on the other hand, can avoid damaging the current collector layer. This ensures the processing precision, speeds up the production and improves the product yield.

Abstract: An active-clamp flyback converter is provided with improved active-clamp switch control that switches on an active-clamp switch at an active-clamp switch on-time that equals a power switch on-time minus a peak charge time for an active-clamp capacitor. The peak charge time is the duration between the switching off of the power switch transistor and when the charging current through the active-clamp capacitor falls to zero. The controller measures this peak charge time following the switching off of the power switch transistor and then applies it to the subsequent switching on of the active-clamp switch so that the active-clamp switch is switched on at the power switch on-time minus the peak charge time.
