The two kW modules communicate with each other to achieve interleaving and current sharing, decreasing the current ripple and reducing the necessary bus capacitance. This allows for a significant reduction of bus capacitors and conductor size.
The high efficiency operation increases the power handling capability of the modules, further increasing the power density of the converter. Each converter module is a fully functional converter, capable of standalone operation. The modules include CAN communication between each module, as well as a separate CAN communication interface to the vehicle system controller. Digital control allows for active tuning of the controller parameters during OEM installation, which allows the converter to be used in most applications without requiring customization.
Currently this converter is available as a kW and kW unit.
