Problems solved by technology

Also, as described in "C. Selection of power switches and diodes", the switches must have low capacitance, because otherwise the zero-voltage switching of the switches may suffer losses, or the leakage inductance of the transformer should be high

Embodiment Construction

[0067] In the following description, numerous specific details are given to provide a thorough understanding of the embodiments. Embodiments can be practiced without one or more of the specific details, or with other methods, elements, materials, or the like. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring aspects of the embodiments.

[0068] Throughout this specification, reference to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, appearances of the phrases "in one embodiment" or "in an embodiment" in various places in the specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures or characteristics may be combined in any suitable manner in one or more embodiments.

Abstract

The present disclosure provides an actuation mechanism for applying a mechanical diode clutch. The actuation mechanism includes a capsule including a cylindrical body defining an interior chamber, the cylindrical body defining a first opening at a first end and a second opening at a second end thereof. The actuation mechanism also includes a pin having a body and a radially- extending arm, the pin being retained within the interior chamber of the capsule. An apply spring is coupled at one end to the pin and a return spring is retained within the interior chamber of the capsule. The return spring is disposed between the pin on one end and the cylindrical body on the opposite end thereof. The return spring substantially surrounds the apply spring.

Description

technical field [0001] The present disclosure relates to electronic converters. [0002] The present disclosure was designed with a particular focus on improving the driving of half-bridge ZETA converters. Background technique [0003] An electronic converter comprising a light source such as at least one LED (Light Emitting Diode) or other solid state lighting device may supply a DC output. For example, such a current can be constant or also varied over time in order to set the brightness of the light emitted by the light source (so-called dimming function). [0004] figure 1 A possible lighting system is shown, comprising an electronic converter 10 and a lighting module 20 (comprising eg at least one LEDL). [0005] For example, figure 2 An example of a lighting module 20 comprising, for example, a chain of LEDs (ie, a plurality of LEDs connected in series) is shown. For example, in figure 2 , shows four LEDL 1 , L 2 , L 3 and L 4 . [0006] Electronic convert...
