Features• 3-phase, 3-level bidirectional AC/DC power converter:

– Rated nominal DC voltage: 800 VDC

– Rated nominal AC voltage: 400 VAC @ 50 Hz– Nominal power: 15 kW

• AC to DC rectifier mode:– Power factor control (PFC) PF > 0.99– Inrush current control and soft start-up

• DC to AC inverter mode:– Active and reactive power control– Integrated grid connection solution

• Power section based on SiC MOSFETs:– High frequency operation (100 kHz)– High efficiency, η = 99%– Passive element weight and size reduction

• Control section based on STM32G474RE microcontroller:– P2P compatible with other STDES 3-phase power converters– 4 integrated high-performance op-amps– Control and monitoring interfaces: SWIM, UART, I²C, DACs– 64-pin Digital Power connector– Overcurrent and overvoltage protection– Configurable topology (2 – 3 levels)

DescriptionThis reference design represents a complete solution for three-phase AC/DC andDC/AC (800 VDC to 400 VAC) applications based on a digital platform optimized forpower conversion.

It is well suited for the Active Front End (AFE) stage in high power charging stations,industrial battery chargers and UPS. The high switching frequency of the SiCMOSFETs and the multilevel structure allow nearly 99% efficiency as well as theoptimization of passive power components in terms of size and cost.

1 Bidirectional converter reference design overview

This reference design consists of the following separate components:• A board with the power converter, LCL filter, sensing circuit, inrush circuit, grid connection management

circuit and on-board auxiliary power supply.• A control module based on the STM32G4 Series microcontroller with connectors for communication and

test-points and status indicators for testing and debugging.

The input and output current and voltage measurements necessary for responsive control are acquired throughisolated measurement blocks, and the STM32 microcontroller manages connection and disconnection with theAC electrical network, as well as load and source DC management in either inverter or rectifier mode.The driving signals for the switching devices are managed by corresponding STGAP2S gate drivers to ensureindependent management of switching frequencies and dead time.The hardware math accelerator in the MCU boosts the trigonometric operations of the voltage oriented control(VOC) algorithm, allowing the power converter to achieve very high power quality.
