Original Abstract Submitted
methods and circuits that enable parallel operation of power converters such that phase shedding is possible without excessively long startup times. more specifically, embodiments utilize reduced gate-drive (rgd) low-dropout (ldo) circuits within individual power converters to enable parallel power converter systems that support phase shedding while eliminating a âping pongâ effect (synchronization problems). the rgd capability of each parallel power converter allows each power converter to come online asynchronously without affecting other parallel power converters. in particular, the rgd capability allows full power up of the power converters with substantially reduced delays for full charge balancing and soft-start. for example, embodiments of the invention typically have delays for rgd charge balancing measured in hundreds of microseconds, not tens of milliseconds as with charge balancing in conventional, non-rgd power converters.
