Bridge isolators
WebFigure 1. Half-Bridge Block Diagram. Ignoring dead time requirements, the other part of the switching cycle has Q 1 on and Q 2 off, meaning V G2S2 < V T, and V G1S1 >> V T.During this time, V OUT swings close to the bus voltage. Note that the source of the high-side switch is connected to V OUT, which means the gate of Q 1 goes above the bus voltage … WebDynamic Isolation Systems is the leader in seismic isolation with over 300 buildings and bridge projects completed worldwide.
