How to use the 15 kW three-level three-phase Vienna rectifier with digital control for power factor correction
Introduction
The STDES-VRECTFD reference design represents a complete solution for high-power, three-phase active front end (AFE) rectifier applications based on the three-level Vienna topology.
This reference design topology is mostly used for DC fast charging applications related to industrial and electric vehicles.
It features full digital control. The embedded STM32G474RET3 mixed-signal high-performance microcontroller provides the full control of the power factor (PF), the DC voltage, and the auxiliary task to manage the protections and the soft start-up procedure.
The high-bandwidth continuous conduction mode (CCM) current regulation allows the maximum power quality in terms of total harmonic distortion (THD) and power factor (PF).

The high switching frequency of the SiC MOSFETs (70 kHz) and the multilevel structure allow an efficiency of almost 99% as well as the optimization of passive power components in terms of size and cost.
The high efficiency rectifier is designed for several end applications such as electric vehicle (EV), industrial battery chargers, and industrial equipment, which requires a very high PF and low THD.
The STDES-VRECTFD is a fully assembled kit developed for performance evaluation only, not available for sale.

Sensing
AC current
An isolated sensor measures the AC input current. It represents the boost inductor current to be controlled for the proper operation of the power converter. Hall sensors are taken into consideration. A conditioning circuit allows obtaining the correct value for the ADCs. The circuit shown below is replicated for each phase.

1.5.2.3.2
AC voltage
The three-phase AC voltages are obtained using a two-stage sensor circuit. The first part represents an isolated op-amp that allows measuring the HV through a voltage divider with an isolation barrier.
Isol-Op-AMP output is limited in volts and is scaled with a second stage of op-amps with a proper gain and bias.
This circuit allows measuring an AC voltage referenced by a virtual or grid neutral point. The circuit is replicated for each phase.

Startup procedure
After connection and debugging initialization, you can perform the startup procedure.
An embedded finite state machine handles this procedure. It consists of different states that perform a preliminary check of the converter and the precharge of the capacitor. Then the burst operation boosts the output voltage.
The STDES-VRECTFD reference design allows managing the complete startup procedure.
However, a controlled step-by-step procedure is available. It is useful during the preliminary test or after hardware/sw modification.

Startup procedure
1.
FSM Wait : PWM signals are in IDLE state, configured in low state, to force all the MOSFETs in off state.
The AC main voltage is already under monitoring. This state is maintained until AC main reaches a lower
AC voltage threshold ( OK_Plug_ACSource ), that is 30 V
AC
. After that, an internal timeout ( TO_IDLE ) is activated to prevent power converter connection during the first-phase synchronization procedure. FSM moves on to FSM Idle .

FSM_Init : handles the inrush current control. If the grid voltage is correct, the status source is equal to
OK_SOURCE . The bulk capacitors are at low voltage and the inrush current must be limited. For this reason, during this state, the inrush relays are considered in series with a high resistance. On the basis of their values, the inrush is completed. The state machine state is still maintained to stabilize the output voltage according to the grid amplitude. After a configurable time, the FSM moves to start state ( FSM_Start ).

This reference design power converter can be represented as a second order dynamic system, which consists of inductors and capacitors. The theoretical different dynamic behavior of this two-system element allows considering two fully decoupling first order systems. For this reason, a current control and a voltage control are taken into account.

Software implementation
Software implementation
The STM32G474RET3 MCU controls the STDES-VRECTFD .
The firmware package is based on the STM32Cube ecosystem. Starting from the STM32CubeMX , all the peripherals and pins used are activated and configured according to the basic project.
The application firmware is supported and tested using STM32CubeIDE , IAR, and Keil development environments.
After the development, the MCU can be programmed through the IDE or STM32CubeProgrammer .
To monitor and control the application, you can use a GUI based on STM32CubeMonitor .
The firmware described in this documentation development is based on the STM32CubeG4 firmware package v1.3.0.
Figure 49. STM32Cube ecosystem development flow
An extensive range of generic and specific firmware modules is available to support the digital power conversion.
The figure below shows the generic development flow to get the power conversion used for the STDES-
VRECTFD firmware development.

UM2975 - Rev 1
This workflow starts from power conversion requirements. This information is then reinterpreted in the application specs that contain information linked to the MCU peripheral and the DPC application configuration.
On the basis of this information, an STM32CubeMX project, properly configured and initialized, is provided. Then, the needed DPC module is included and configured.

Configuration files
The STM32CubeMX generates the development IDE project. The MCU is directly flashed through the IDE or
STM32CubeProgrammer . At the end of this operation, the DPC application is tested and debugged through
STM32CubeMonitor . The digital power converter firmware is then released, if compliant, and the DPC is adapted.
The STDES-VRECTFD reference design power converter allows managing the energy flow. The figure below shows the algorithm schematic diagram of the implementation in the AC-DC rectifier application.
