Abstract: A power conversion unit includes power converters arranged sequentially to each other to convert input power that is provided at an input of the power conversion unit to output power. A set of first capacitors are arranged in series with each other and include, for each power converter, a first capacitor that is arranged in parallel with an associated power converter. Each first capacitor is also arranged to store a portion of the input power. A set of second capacitors are connected in series with each other and include a second capacitor connected between each pair of sequential power converters in the sequence. The set of second capacitors are arranged to balance the portion of the input power stored by each first capacitor.

Abstract: Methods, systems, and apparatus for circuit breakers with integrated safety, control, monitoring, and protection features. In one aspect, a circuit breaker includes an input and an output, a switch coupled between the input and output, a communications device configured to communicate on a data communications network, and a control system coupled to the switch and the communications device, wherein the control system is configured to perform operations including opening the switch as a consequence of detecting an overcurrent condition in a circuit downstream from the circuit breaker, opening and closing the switch based on one or more instructions received by the communications device from the data communications network, and monitoring the power consumption of the circuit downstream from the circuit breaker.
