Reconfigurable converter for multiple-level input-line voltages
A switchable power converter includes an input section that receives an AC input voltage and rectifies the AC input voltage and a switchable converter section operative to receive the rectified AC input voltage and convert the rectified AC input voltage to an intermediate DC output voltage. The switchable converter section includes at least one configuration switch operative to switch the switchable converter section between a boost converter topology, for low input line voltages, and either a flyback or SEPIC converter circuit topology, for high input line voltages.
