What does ACM stand for?

Average current mode interleaving allows a system to achieve between 50 and 100 percent reduction in ripple compared to today's typical non-interleaved PFC architectures.

To extend MTBF, average current mode control is used to implement droop sharing between converters without any single point failure modes, thus enabling N+1 redundancy.
