摘要： A modular load management system comprises one or more compact modules designed to fit in the wiring troughs of a standard AC distribution panel of a building. The modules include one or more input terminals to receive electrical power from one or more circuit breakers in the panel and deliver power to load circuits of the building via one or more output terminals. The modules contain at least one disconnect switch for disconnecting circuits from breakers in response to a remote or locally-generated control signal. The modules may also include current sensors on some or all terminals, such that power and energy flow may be monitored on a per-circuit basis.

摘要： An apparatus such as a power converter includes a first flying capacitor, a second flying capacitor, etc., an inductor, and a network of switches. The network of switches controls conveyance of energy from the multiple flying capacitors to the inductor. The inductor converts the received energy into an output voltage to power a load. A magnitude of the respective voltage on each of the flying capacitors is substantially the same.

摘要： A voltage monitor circuit that signals if an input voltage is above or below an internally established reference level proportional to the bandgap voltage of silicon. The voltage monitor circuit mitigates main error sources generally associated with bandgap reference generation such that high accuracy and good performance may be achieved at low power cost. The techniques allow voltage monitors (e.g., brown-out and power on reset (POR) detectors) to be implemented with higher accuracy, lower power consumption, smaller area cost, and support to lower supply voltage than other solutions.
