    摘要: Methods, systems, and devices are described for using isolated and non-isolated circuit structures and control methods for achieving multiple independently regulated input and output parameters using a single, simple, primary magnetic circuit element. For example, structures and methods are revealed for achieving single-stage power factor correction with high power factor and multiple independently regulated outputs using a single, simple, primary magnetic circuit element. Other structures and methods are revealed for achieving multiple independently regulated outputs without power factor correction using a single primary magnetic circuit element for both isolated and non-isolated power conversion applications.

    摘要: Methods, systems, and devices are described for using coupled inductor boost circuits to operate in a zero current switching (ZCS) and/or a zero voltage switching (ZVS) boundary mode. Some embodiments include a coupled inductor boost circuit that can substantially eliminate rectifier reverse recovery effects without using a high side primary switch and a high side primary switch driver. Other embodiments include a coupled inductor boost circuit that can achieve substantially zero voltage switching. ZCS and ZVS modes may be effectuated using control techniques. For example, a magnetizing current may be sensed or otherwise represented, and a signal may be generated accordingly for controlling switching of the controller.

    摘要: A method and structure for a non-reopening extruded plastic profile fastener wherein complementary rib and groove type profiles are constructed and arranged to be pressed into interlocking relationship, and provided with restraining means against permanent interlocking so that the fastener can be handled as an assembly with the profiles aligned for interlocking but not interlocked until the means are overridden and the profiles pressed into interlocked relation with one form of the overridable means being a frangible diaphragm across the groove to prevent movement of the rib and in another form a projecting strut which is yieldable with the application of a predetermined force or which is removable to permit the profiles to be moved to fully interlocked position.
