Self synchronizing power converter apparatus and method suitable for auxiliary bias for dynamic load applications

An auxiliary power supply or bias voltage supply employs a step up switch mode DC / DC power converter topology to supply regulated bias supply voltages, from very low input voltages (e.g., less than 2V). The supply will synchronize to dynamic loads making it particularly useful in circuits with periodic high peak current power demands, for example, gate drive circuits employed in regulated switched mode power converters. When unladed, the supply will efficiently adjust its cycle period to the minimum required to maintain the desired boosted output voltage. Additional transformer windings or a charge pump may be used to generate additional vias voltage sources.

Connector having floating structure

A connector assembly having a floating structure includes a connector moveably mounted in a cradle housing. A part of this connector connects to and detaches from another connector facing, through a spacing, a connector-mounting window of the cradle housing. The connector on the moveable side is moveable freely within the range of the spacing. An elastic member of flexible material is provided on the exterior of the moveable-side connector and closely contacts and is housed in a housing part formed in the cradle housing. An elastic member restoring force, acting when coupling between the moveable-side connector and the other connector is released, causes the moveable-side connector to return its original position in the cradle housing.
