A system includes a first buck type direct current (DC) to DC converter having: a first control switch; a first synchronized switch; an inductor; and a capacitor. The system further includes a second buck type DC to DC converter having: a second control switch; a second synchronized switch; the inductor; and the capacitor. The system further includes a controller operatively connected to the first buck type DC to DC converter and the second buck type DC to DC converter, wherein the controller controls a conduction state of the first control switch and the second control switch; and an output terminal pair operatively connected to the capacitor.

Dual source DC to DC converter

A system and method of monitoring a photovoltaic (PV) installation includes providing a string of multiple panel interface device enabled PV panels; operatively connecting an inverter to the string; operatively connecting at least one PV panel to the string; discharging an input capacitance of the inverter; comparing a current in the string to a predetermined current threshold value; and controlling connection of the at least one PV panel to the string based on the comparing of the current in the string to the predetermined current threshold value. A panel interface device may be used to discharge the input capacitance of the inverter.

String continuity monitoring

An electrical circuit and method includes a transmitter in a first power domain with a first supply voltage referenced to a first voltage reference. The transmitter has an oscillator generating a first carrier signal, and an analog modulator receiving an input sensor signal and the first carrier signal and generating a modulated carrier signal. A receiver is in a second power domain with a second supply voltage referenced to a second voltage reference. The second voltage reference is different from the first voltage reference. The receiver includes a demodulator that receives and demodulates the modulated carrier signal and generates an output sensor signal. At least one coupler includes a pair of galvanically isolated elements with one galvanically isolated element in each of the first and second power domains. The modulated carrier signal couples from the first power domain to the second power domain through the at least one coupler.
