Abstract
Uncompensated upper and lower reference-currents are generated for first and second branches of a high-frequency half-bridge within an interleaved-totem-pole PFC. A first control-signal for the first branch is generated from comparison between an inductor-current and uncompensated reference-currents for the first branch, a first timing-reference is generated from the first control-signal from a number of active branches, a compensated upper reference-current is generated for the second branch by adding a first compensation-current to the uncompensated upper reference-current for the second branch, a compensated lower reference-current is generated for the second branch by subtracting the first compensation-current from the uncompensated lower reference-current for the second branch, a second control-signal is generated for the second branch from the compensated reference-currents for the second branch, a first timing-difference is generated from a phase-difference between the first and second control-signals, and the first compensation-current is generated from a difference between the first timing-reference and timing-difference.
