    For those unfamiliar, the basic concept for bucks, boosts, etc. goes like this: you turn a switch on to build current in an inductor, then you put that inductor in a state where it discharges some or all of its current into a capacitor, which stores the energy from the inductor current as charge at some voltage. For higher loads, you either do this more often or you put more current in the inductor each time.

    An inductor stores kinetic electrical energy in the magnetic field, and a capacitor stores potential energy in the electric field. Moving energy between these domains is the main trick of switching converters.

    LEDs driven by AC without transformers or rectifiers

    Running LEDs from an AC supply
    May 2, 2006
    In most applications, LEDs are driven by a DC power supply, but AC offers several significant advantages. Lynk Labs has developed technology that allows LEDs to be driven directly from an AC supply.

    If you need to send data from sensors, there are plenty of options, including a bewildering selection of wireless methods. Trouble is, most of those protocols require a substantial stack of technology to make them work, and things aren’t much easier with wired sensors either. It doesn’t have to be that complicated, though, as this simple two-wire power-and-data interface demonstrates.

    As with all things electronic, there are tradeoffs, which [0033mer] addresses in some detail in the video below. The basic setup for his use case is a PIC-based sensor — temperature, for this demo — that would be mounted in some remote location. The microcontroller needs to be powered, of course, and also needs to send a signal back to a central point to indicate whether the monitored location is within temperature specs. Both needs are accommodated by a single pair of wires and a tiny bit of additional circuitry.
