STEVAL-ISF001V2 New 3 kW FOT PFC based on the L6563S and STW88N65M5
The STEVAL-ISF001V2 demonstration board provides a compact and ready-to-use solution for the implementation of a simple PFC system able to supply loads with a power close to the maximum delivered in the most typical domestic installations.
For such a power range the use of a continuous mode PFC operation becomes mandatory in order to drain from the net a current with an RMS value that does not surpass the maximum allowed from the metering system and to have a reasonable device size involved in the system operations.
Normally, the use of a standard continuous mode driver chip means the use of a more expensive and complex driver along with all the passive components required.
STMicroelectronics has patented a solution that allows the use of a simple driver, designed for transition mode operation, in a fixed off-time, variable frequency, PWM modulation.
This kind of modulation gives a current on the boost inductor of the PFC that is comparable with the current obtained using a classic continuous mode modulation.
