Bidirectional isolated universal topology (BIUT) high power DC-DC converter assemblies and systems balance voltages and control currents between high power DC sources and high power DC loads where at least some of the high power DC sources are alternative energy or renewable energy power supplies and high power DC loads associated with alternative energy or renewable energy. The BIUT high power DC-DC converter assemblies and systems are capable of reversing current flow direction where loads become the sources and sources become the load in DC power systems where the supplies and loads are all connected to a common DC voltage bus.

An integrated multi-mode, large-scale electric power support system supplies on demand at least 2,500 kW to an electrical grid with low harmonic distortion either from co-located solar or wind renewable energy DC power sources or in combination with, or alternatively, from system stored energy DC power sources via a plurality of DC-to-AC inverters with phase-shifted outputs. The power support system can also inject on demand grid power factor correcting reactive power. An alternative high voltage power support system can supply on demand at least 50 megawatts to the grid.

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.

An apparatus and process are provided for controlling the heating and melting of a material that is non-electrically conductive in the solid state and is electrically conductive in the non-solid state. Power is selectively directed between coil sections surrounding different zones of the material in a susceptor vessel by changing the output frequency of the power supply to the coil sections. Coil sections are at least one active coil section, which is connected to the output of the power supply, and at least one passive coil section, which is not connected to the power supply, but is connected in parallel with a tuning capacitor so that the at least one passive coil section can be selectively operated at, or near, resonant frequency when the transition material in the vessel is molten. Depending upon the state of the transition material in the susceptor vessel, the frequency of the power applied to the active coil section can be changed to generate a magnetic field that selectively couples with the susceptor vessel, transition material in the vessel, and/or the passive coil section.

Solid or semi-solid feedstock is melted in an open bottom electric induction cold crucible furnace. Directionally solidified multi-crystalline solid purified material continuously exits the bottom of the furnace and may optionally pass through a thermal conditioning chamber before being gravity fed into a transport mold where an ingot of the purified multi-crystalline solid material is transported to a remote holding area after the transport mold is filled with the multi-crystalline material and cut from the continuous supply of material. Cool down of the ingot is accomplished remote from the open bottom of the electric induction cold crucible furnace.
