Paralleling of converter power modu

Paralleling of converter power modules is a well-known technique that is often used in
high-power applications to achieve the desired output power with smaller size power
transformers and inductors [B1]. Since magnetics are critical components in power converters
because generally they are the size-limiting factors in achieving high-density and/or low-profile
power supplies, the design of magnetics becomes even more challenging for high-power
applications that call for high power-density and low-profile packaging. Instead of designing
large-size centralized magnetics that handle the entire power, low-power distributed highdensity/
low-profile magnetics can be utilized to handle the high processing power, while only
partial load power flow through each individual magnetics
