Abstract
A drive circuit comprises a transformer, a primary side circuit communicating with a primary winding of the transformer, and a secondary side circuit communicating with a secondary winding of the transformer. The primary side circuit couples to a primary side supply voltage and to an input signal and couples a first signal to the primary winding. The secondary side circuit communicates with the semiconductor switch and provides, responsive to the first signal, a second signal to control the semiconductor switch, comprising at least one of a primary bias and a secondary bias. For a first gate charge level range, the secondary side circuit provides the primary bias. For a second gate charge level range greater than the first range, the secondary side circuit is controlled by a secondary bias circuit comprising a storage capacitor configured to accumulate voltage when the secondary side circuit is providing the primary bias.

Documents recorded with the USPTO Assignment Recordation Branch that list this patent. A security interest is a lender’s claim on the patent as collateral; a release ends it.
USPTO bulk data: PatentsView granted patents, disambiguated (PVGPATDIS) for patents, assignees, inventors, places and CPC categories; the USPTO Patent Assignment Dataset (ECORSEXC) for assignments and security interests. Patents filed in the last 20 years. No claims or full text. Links to other records are by name (and state): EXACT means the identical full name and state; FUZZY means a looser name match, with the confidence shown.
