摘要： Apparatus and method are provided for electric induction heating and melting of a transition material that is non-electrically conductive in the solid state and electrically conductive in the non-solid state in an electric induction heating and melting process wherein solid or semi-solid charge is periodically added to a heel of molten transition material initially placed in a refractory crucible. Induction power is sequentially supplied to a plurality of coils surrounding the exterior height of the crucible at high power level and high frequency with in-phase voltage until a crucible batch of transition material is in the crucible when the induction power is reduced in power level and frequency with voltage phase shifting to the induction coils along the height of the crucible to induce a unidirectional electromagnetic stir of the crucible batch of material.

摘要： Electric power from typically unstable multiple dc sources is converted to ac electric power of suitable quality for injection into an electric power grid. Conversion is accomplished by current regulation of the output from the dc sources to the input of each one of multiple inverters in a system, with each inverter outputting multiple phase currents that are out of phase with the multiple phase currents outputted from all other inverters in the system. The multiple phase currents from all of the inverters in a system are connected to the secondary windings of a phase transformation network that produces a three phase current output having a step-shaped waveform for injection into the electric power grid.

摘要： Power from the dc outputs of wind-generated power collection nodes is converted to ac power of suitable quality for injection into an electric power grid. Conversion is accomplished by current regulation of the dc outputs of the wind-generated power collection nodes to the input of each one of multiple inverters in a system, with each inverter outputting multiple phase currents that are out of phase with the multiple phase currents outputted from all other inverters in the system. The multiple phase currents from all of the inverters in a system are connected to the secondary windings of a phase transformation network that produces a three phase current output having a step-shaped waveform for injection into the electric power grid. Alternatively the dc input to each one of the multiple inverters may be a combination of the dc outputs of wind-generated power collection nodes and the dc outputs of solar photovoltaic power collection nodes.

摘要： An induction heating and melting system uses a crucible formed from a material that has a high electrical resistivity or high magnetic permeability, and one or more inductor coils formed from a wound cable consisting of multiple individually insulated copper conductors to form an induction furnace that, along with its associated power supply, provides a compact design. The system components are air-cooled; no water-cooling is required. The crucible may alternatively be shaped as a tunnel or enclosed furnace.

摘要： A system for melting metal and holding molten metal, comprises a rectifier unit receiving AC electric power and outputting DC electric power, a plurality of inverter units, each receiving the DC electric power output by the rectifier unit and outputting AC electric power; and a plurality of induction furnaces each receiving the electric power output by a respective inverter unit. Each inverter unit comprises a plurality of inverter modules connected in parallel, each module independently being connectable to and disconnectable from the rectifier unit and the furnace. The rectifier unit comprises a plurality of rectifier modules connected in parallel, each module independently being connectable to and disconnectable from the AC supply and the inverter units. The total power output of the rectifier unit is more than the sum of the powers required by all of the furnaces when they are holding a charge of molten metal, but less than the sum of the maximum powers required by each furnace when melting a charge of metal. If the total power demand is greater than the rectifier can supply, the power supply is reduced to those furnaces that are receiving more than the holding power.
