3.2.1.4. Clarke and Park Transforms

The Three-phase Boost Bidirectional AC/DC Converter for EV Charging design example uses Clarke and Park transforms to convert current and voltage three-phase values to DC signals. The transforms establish three phases as vectors on a two-dimensional rotating coordinate system. The coordinate system rotates at the same rate as the voltage and current vectors.

For power conversion, controlling voltages and DQ frame current allows controlling the level of reactive and active power, giving the ability to control the power factor independently.

The following image shows the implementation of Clarke and Park transforms using Simulink blocks in discrete time for FPGA implementation using HDL coder:
