2 How to use the STDES-PFCBIDIR reference design
2.1 System setup
To use the STDES-PFCBIDIR , you need:
• a programmable AC emulator or a programmable AC source;
• a DC electronic load;
• a power analyzer;
• a digital oscilloscope.
You can test the STDES-PFCBIDIR up to 15 kW at 230 V
AC
RMS and 6 kW at 110 V
AC
RMS in a frequency
between 47 and 63 Hz.
2.2 How to connect the reference design
To operate the reference design power converter properly, consider the operating limits shown below.
Table 4. Operation condition limits
Description Value Unit
Three-phase input voltage range 208-400
V
AC
Line frequency range 47-63 Hz
Maximum output power at 230 V

15 kW
Voltage limit of the bulk capacitors 500 V
Step 1. Connect the power board as shown in the figure below.
The figure shows the three-phase connection sequence (A-B-C). The neutral connection is optional.
The power board handles the input connection exploiting the four input relays. The polarity influences
the DC load connection.

Step 2. The auxiliary power supply can be externally provided. Connect an external fan to manage the thermal
dissipation.
