Input Converter:

The typical use for this converter configuration is an active rectifier for grid tie, an alternator, PMG, or wind turbine.  However it can also be used for DC inputs such as batteries and solar cells.  The topology is a 3 phase SiC bridge design with a standard frequency range of DC to 400 Hz with options exceeding 1 kHz.  

Through the programmability of this unit it can also serve as a line regulator, VAR compensators, or harmonic injection device for AC grids.

This converter has an auxiliary connector that allows the user to have functions such as syncing multiple units or testing their own waveforms.

DC to DC Converter:

This configuration is used to isolate DC voltages.  This SiC based converter is bi-directional and operates at frequencies of 50 kHz to over 100 kHz.  High isolation, low coupling capacitance versions are available. 

Output Converter:

The typical use for this converter configuration is a voltage or current source that can be set to output AC or DC for lab use.  However, it can be used to control motors, make micro girds, control batteries, and test your own algorithms.  This is also 3 phase SiC bridge design.  Standard output frequencies go from DC to 400 Hz with higher frequencies available.  With an actively controlled split DC link the outputs can have DC imposed on the AC outputs.

The auxiliary connector adds flexibility such as resolver, encoder, and motor angle calculations that can be used for motor testing and control.  The analog inputs can control the output frequency and magnitude making the unit into a large PWM amplifier.  Another mode of operation is the direct PWM control where the operator can use their own PWM inputs to control the outputs directly.

Master Controller:

The master controller allows for paralleling many converters.  The outputs of the converters are synced in a way that they can be paralleled and properly share the load.  With this option multi-megawatt systems can be constructed.
