Single-phase & multiphase setup

Single-phase setup

The basic building blocks comprising a functional power half-bridge include two power transistors (e.g. MOSFETs), gate drivers for high-side and low-side MOSFETs, and a control unit (e.g. XMC microcontroller). Mother boards of the modular platform provide the gate drivers for the system. A single mother board is used for any individual phase. The distinct feature of the master mother board is that it also provides the supply and direct interconnection to the control board, whereas mother boards connect to the control board indirectly via the ribbon cable through the master mother board, and do not include a supply circuit.

Single-phase setup no paralelling

This is the single-phase set-up that can be used as a buck or boost converter topology, with or without synchronous rectification

Single-phase setup with paralleing

Additional power boards (half-bridges) can be connected in parallel, to increase the current handling capabilities. To do this, the same number of daughter boards are required to provide connections from the MOSFETs to the gate driver on the master mother board.

Multiphase setup with paralleling

Also known as the B6 inverter, this is a three-phase system used for electric motor control. The gate drivers for the additional two phases (“W” and “V”) are provided using two mother boards. The mother boards are connected via a ribbon cable to the master mother board. The master mother board provides the gate driver for phase “U”, and extends the connections between the ribbon cable, which connects to the mother boards, and the control board outputs
