Abstract :
A highly efficient 1.5 kW power factor correction converter for computer applications is presented. Eight boost-topology
switching cells are interleaved to meet stringent EMI input ripple specifications while operating at a very low switching
frequency (25 kHz per cell) to minimize switching losses. The result is a system with very high conversion efficiency (94%-97%,
including input bridge, bias supply, and EMI filter losses) over the 93-264 VAC input range. Key implementation details, including
discontinuous inductor current operation, a combination of linear and bang-bang control algorithms for fast dynamic load response,
and extended (100 ms) power outage ride-through capability, are described.
