  • System and method for starting up a high density isolated DC-to-DC power converter
    Patent number: 10483858
    Abstract: A DC-to-DC power converter includes a transformer having a primary side and a secondary side, and a primary circuit electrically coupled to the primary side of the transformer. The primary circuit includes a primary microcontroller configured to generate a first energizing signal that energizes a portion of the primary circuit. The DC-to-DC power converter also includes a secondary circuit electrically coupled to the secondary side of the transformer. The secondary circuit includes a secondary microcontroller communicatively coupled to the primary microcontroller, wherein the secondary microcontroller is configured to provide an instruction to the primary microcontroller that causes the primary microcontroller to relinquish control of the primary circuit to the secondary microcontroller, and wherein the secondary microcontroller is further configured to provide a second energizing signal to the portion of the primary circuit.

  • Integrated magnetic assemblies and methods of assembling same
    Patent number: 9991043
    Abstract: An integrated magnetic assembly includes a magnetic core, an input winding inductively coupled to the magnetic core, a first output winding inductively coupled to the magnetic core, and a second output winding inductively coupled to the magnetic core. The magnetic core includes first and second non-winding legs, and first and second winding legs. The first and second non-winding legs are spaced apart from one another, and the magnetic core defines an opening between the first and second non-winding legs. The input winding extends through the opening between the first and second non-winding legs, and is wound around each of the first and second winding legs. The first output winding is wound around the first winding leg. The second output winding is wound around the second winding leg.
