  • Patent number: 11984846
    Abstract: A power conversion circuit is used in a solar array suitable for, e.g., roadside adjacent installation. The power conversion circuit includes an inverter with a first stage electrically coupled to one or more solar panels. A third stage of the circuit has a DC to AC converter that provides less than a 50 VAC load voltage to a load, and a second stage that is coupled between the first and third stages and provides an isolated electrical power coupling therebetween. A sync interface communicatively couples a controller to other controllers dedicated to one or more other respective inverters of the solar array via a sync signal. The controllers synchronize the third stages of the inverters via the sync signal. The third stages of the inverters are coupled in series to provide a load output voltage.

  • Patent number: 11162715
    Abstract: Standalone and self-contained cooling systems using compressed liquid and/or gas CO2 containers positioned in an insulated or non-insulated vessel encompassing a container which is either vertically positioned in an upright or an upside-down position. The liquid and/or gas CO2 coolant is then released into a capillary system or flow metering system to allow the CO2 to enter a second body to where the CO2 coolant properties may be leveraged. The second body includes, by way of example, a plate, a cushion, a spot treatment pad for a person's muscle, or a cooler. The temperature is controlled by a metering CO2 releasing system encompassing an electronic control device which sends alerts when pre-defined thresholds are exceeded. The invention's metering CO2 releasing system may be triggered by an electronic or a thermostatic valve or may be triggered manually or by an electronic solenoid.
