protection. When the voltage on this pin is above 1 V, gate driver signals are actively pulled low. After the voltage falls below 0.6 V, the gate driver signal recovers with a soft-start. Pin 5 and 8 are connected to the primary side of the gate driver transformer to drive the half-...
transformer core or to sense the DC current through the transformer to provide adjustment of the fluxbucking current. The disclosed transformer circuit is a bridge configuration which cancels the DC flux independently in separate primary windings, and is advantageously employed in telephone line circuits...
5.2. Comparison to Transformer Models A Norton equivalent of a synchronous machine will be more similar to transformer models. One similarity is the treatment of the magnetization as a shunt inductance. This magnetization shunt branch is in parallel with the load current (see Figure 32, with I ...
