EVAL_3K3W_TP_PFC_SIC

3300 W CCM bidirectional totem-pole PFC unit using CoolSiC™ 650 V, 600 V CoolMOS™ C7, and digital control via XMC™ microcontroller

OPN: EVAL3K3WTPPFCSICTOBO1

Infineon board components:

• CoolSiC™ trench MOSFET 650 V (IMZA65R048M1)
• 600 V CoolMOS™ C7 SJ MOSFET (IPW60R017C7)
• EiceDRIVER™ gate-driver IC (2EDF7275F)
• Quasi-resonant flyback PWM controller (ICE5QSAG)
• ​950 V CoolMOS™ P7 SJ MOSFET (IPU95R3K7P7)
• 32-bit microcontroller (XMC1404-F064X0200AAXUMA1)

This evaluation board is a system solution for a bridgeless totem-pole power factor corrector (PFC) with bidirectional power capability.
The EVAL_3K3W_TP_PFC_SIC is enabled by Infineon’s CoolSiC™ and CoolMOS™ Superjunction power MOSFETs as well as isolated drivers and an XMC™ microcontroller.

Target applications are those requiring high efficiency (~99%) and high power density (72 W/in³), such as high-end server and telecom. In addition, the bidirectional power flow capability allows to address battery chargers or battery formation applications.
The integrated totem-pole operates in continuous-conduction mode (CCM) in both, rectifier (PFC) and inverter mode which also implements digital control on Infineon’s XMC™ 1000 series microcontroller.

Target applications: high-end server, datacenter, telecom

Features:
 

• High efficiency bridgeless totem-pole PFC
• High power density
• Enabled by CoolSiC™ trench MOSFET 650 V
• Digitally controlled via XMC1404
• Bidirectional capability (DC-AC operation)

Benefits:

• Efficiency close to 99%
• Compact form factor (72 W/in³)
• Low component count
