Global flow behaviors of multiple shafts in shallow-buried urban road tunnels subjected to fire load

Underground Space
Shallow-buried urban road tunnels with shafts (URTS) have reduced traffic congestion in large cities. During fire scenarios, the backflows occur at those shafts far away from the fire source inhibiting smoke exhaust, but its rules have been unknown.

A bidirectional AC-DC converter for charging piles with a backflow power optimization control strategy

Journal of Physics: Conference Series
Abstract This paper proposes a single-stage isolated converter with a backflow power optimization method for V2G charging piles. The modulation algorithm is optimized, and the phase shifts are designed to minimize the backflow power. Due to the suppression of backflow power during the switching period, the power factor correction (PFC ...
