Boost converter having multiple outputs and method of operation thereof

A method of converting an input voltage into first and second output voltages, comprising:

• (a) receiving said input voltage into a first switching circuit coupled to a first rail of said input and having a first switch and a first capacitor coupled in parallel;
• (b) next receiving said input voltage into a boost inductor;
• and
• (c) next receiving said input voltage into a second switching circuit coupled to a second rail of said input and having a second switch and a second capacitor coupled in parallel, said boost inductor coupled in series between said first switching circuit and said second switching circuit to provide a conductive path for said input DC voltage to flow serially through said first switching circuit and said second switching circuit to charge said first and second capacitors, respectively.

A power converter, comprising:

• a rectifier, couplable to a source of AC power, that provides rectified DC voltage;
• a boost converter, coupled to said rectifier, that converts said rectified DC voltage received at an input thereof into first and second output voltages provided at first and second outputs thereof, respectively, including:
• a first switching circuit coupled to a first rail of said input and having a first switch and a first capacitor coupled in parallel,
• a second switching circuit coupled to a second rail of said input and having a second switch and a second capacitor coupled in parallel, and
• a boost inductor, coupled in series between said first switching circuit and said second switching circuit, that provides a conductive path for said input DC voltage to flow serially through said first switching circuit and said second switching circuit to charge said first and second capacitors, respectively;
• a first DC/DC converter, coupled across said first capacitor, that converts said first output voltage into a first regulated DC voltage;
• and
• a second DC/DC converter, coupled across said second capacitor, that converts said second output voltage into a second regulated DC voltage.
