› In a st<strong>and</strong>ard boost PFC the input stage is still today using diodes since:<br />

› No need for control signal;<br />

› HV mosfets so far didn’t have a low enough Rds-on vs price to become competitive<br />

versus diodes. Now the use of new generation technologies or new material allows<br />

this.<br />

Power dissipated in the input bridge is high compared to the global balance;<br />
