This New Product Brief (NPB) is part of a video series highlighting the features, applications, and technical specs of newly-released products.
INFINEON 3300W Bridgeless Totem-Pole PFC Evaluation Board
Infineon Technologies 3300W Bridgeless Totem-Pole PFC Evaluation Board is a complete bidirectional AC/DC power conversion solution for high-end applications that require high power density and the highest efficiency.
The totem-pole design is based on Infineon’s 650V CoolSiC and 600V CoolMOS Superjunction Power MOSFETs with isolated gate drivers, while an XMC 1000 family MCU provides full digital control.
Conversion direction is selected with a switch next to the MCU, and the board operates in continuous conduction mode in both rectifier and inverter mode with a fixed 65kHz switching frequency. The design can operate above 99% efficiency and manages a power density of 73W/in3.
It also includes a bias board based on an Infineon CoolSET QR Flyback Controller and 950V CoolMOS Superjunction MOSFETs.
- Enabled by 650V CoolSiC and 600V CoolMOS C7 Power Transistor
- Digitally controlled by XMC1404 MCU
- Bidirectional capability: AC/DC (rectifier) or DC/AC (inverter)
- Switch by MCU selects operation mode
- Up to 99% efficiency
- Supply voltage: 176V to 265V
- Power density: 73W/in3
- Max output power: 3300W
- Output voltage: 300V to 450V
- Bias board based on CoolSET QR Flyback Controller and 950V CoolMOS SJ MOSFETs
