NOVELTY - The device has a secondary special circuit which provides a grid referenced alternating (AC) voltage output to main distribution panel. A resistor ladder is connected to the pulse width modulator whose outputs are provided to opto-isolators whose outputs are connected separately to the MOSFET driver. A tertiary special circuit provides positive and negative DC voltages from an upconverter secondary transformer to DC bus using full wave bridge rectifier with four diodes each arranged to provide a corresponding positive or negative output to DC bus.    USE - Device for connecting thermoelectric generator powered facility such as home, apartment complex, business, solar power station and wind power station (all claimed) to electric power company grid.    ADVANTAGE - The special circuit prevents power feed back into the grid when the grid is down and being repaired. The efficiency for conversion of heat energy to electrical energy for home is improved by making use of n-doped and p-doped semiconductors attached to metal heat-conducting elements in a circular arrangement of thermoelectric components.    DETAILED DESCRIPTION - A multiple-pole double-throw switch installed between electrical grid lines and primary special circuit allows the facility to connect only to the grid. The output of positive voltage reducing full wave bridge and the output of negative voltage reducing full wave bridge are each separately connected to ground by a capacitor. A neon bulb is provided between triac and a fixed resistor in light dimmer circuit. A selection switch is connected to pulse width modulator and a thermoelectric generator is powered from a heat storage reservoir. An adjustable control grid inputs and outputs to and from the thermoelectric generator. An INDEPENDENT CLAIM is included for solar power utility grid-attached energy system has a sun tracking parabolic focusing reflector with focal point target. A heat transfer system has a closed loop of re-circulating air between insulated heat store and focal point target. A heat store (41) of particulate solids has a fan controlled re-circulating loop of air between heat store and closed chamber around hot fins of a thermoelectric generator. A remote control for speed of fan transfers heat between heat store and closed chamber of thermoelectric generator. A control panel reads the voltage of grid and manually controls the speed of fan transferring heat from heat store, reads the voltage of each leg of the grid input lines and generator output lines. A rheostat adjusts the grid voltage of each leg supplying the generator. The remote control utilizes latching triac switches in each leg of the connection to grid in the latching triac switches are remotely controlled. The remotely controlled switches are controlled by utility using wireless telephone communications and over-the-grid electronic communications.
