| Input voltage | 24 V |
| Output 1 | 40 V |
| IC revision | 1.0 |
Description
It is a low voltage digital power factor corrector evaluation board to be used with a compatible NUCLEO board from STMicroelectronics.This board implements a high performance but fully digital PFC pre-regulator power stage in the form of a single phase CCM ToTem Pole, or a dual-phase/interleaved CCM ToTem Pole. It is implementing the GAN technology transistors, from STMicroelectronics, and supporting high switching frequency.This board aims for demonstration and training purpose of this new topology.
Features
- Continuous Conduction Mode (CCM) Power Factor Correction (PFC) power stage
- Single or two-phases interleaved ToTem Pole converter operation
- 24 Vac nominal input voltage
- 0-40 Vdc maximum output voltage
- Max power 16W (using on board load)
- On-board resistive loads (25% + 25% + 50%)
- Injection points for measurement of the voltage loop and current loop using a vector network analyzer
- Numerous Tests Points for measurements such as ISRs duration, PWMs signalisation, Input and Output voltages, Input current in each Legs , ZCD, etc.
- Compatible with the STM32G474RT6 nucleo board
Typical applications
- Demonstration and training purposes
