Abstract: A system includes a power electronics and storage device coupled to one or more photovoltaic (PV) modules, one or more batteries, and an output power bus. The power electronics storage and storage system includes power electronics configured to control a voltage/current curve at an output port according to a selected operating mode of a plurality of operating modes. The operating modes one or more of a PV emulation mode, a parallel and series connection mode, a battery emulation mode, a battery cell voltage scaling mode, or other modes. The power electronics may include a microcontroller to control one or more of a port voltage at an output port and a common voltage at a shared or common node to manage power flow to, from, and between a PV port, a battery port, and the output port.

Abstract: A non-linear integrated phase locked loop circuit includes a phase detector for receiving a data signal and a clock pulse and for outputting a pump-up signal and a pump-down signal, a pulse divider connected to the phase detector for receiving the pump-up signal and the pump-down signal and producing a first output at predetermined multiples of the pump-up signal and a second output at predetermined multiples of the pump-down signal. A pulsed filter or integrator is connected to the pulse divider for receiving the first output and the second output and providing a frequency control signal for a voltage controlled oscillator. A three state amplifier is connected to the phase detector for receiving the pump-up signal and the pump-down signal and providing a phase control signal for a voltage controlled oscillator. The voltage controlled oscillator is connected to the pulsed filter and the amplifier for receiving the frequency control signal and the phase control signal and producing a corresponding output.
