Abstract: A dwelling power management system includes a smart power integrated node located at a dwelling and configured to transit information to and receive information from a remote server arrangement. The smart power integrated node selectively controls power applied to dwelling electrical power hardware components according to a recommended operating procedure (ROP). The system also includes a utility switch connected to the smart power integrated node, the utility switch configured to control distribution of electrical power received from a dwelling external power source. The smart power integrated node transmits dwelling power usage information and dwelling user preferences to the remote server arrangement that evaluates relevant information including dwelling power usage information and dwelling user preferences and dwelling external factors to develop an optimized ROP. The smart power integrated node operates according to the optimized ROP.

Abstract: A multiple stage switching type converter circuit provided between an AC source and a DC source is provided. The circuit includes a boost converter stage coupled to the AC source, a DC link capacitor stage comprising a DC link capacitor decoupled from an AC source and a DC source, and an isolated DC-DC converter stage coupled to the DC source. The multiple stage switching type converter circuit comprises a plurality of switches, each switch configured to operate at a baseline duty cycle, a baseline voltage, a baseline resistance, with a baseline current and providing a baseline switching time. At least one switch is altered to perform at a duty cycle differing from the baseline duty cycle, a voltage differing from the baseline voltage, a resistance differing from baseline resistance, with a current differing from the baseline current or using a switching time differing from the baseline switching time.
