Circulating currents in a delta winding

2018/7/31Now getting back to zero sequence current, if the xfmr is Y-Y, no delta tertiary, an unbalanced load on the secondary from line to neutral will result in the 3 phase voltages going out of balance. With 3 phase shell type core, or 3 single phase units ganged together for 3 phase operation, the Y-Y configuration is avoided, since it cannot support an unbalanced load with only 3 wires. Get price

The Basics of Autotransformers

The load current is 20A at 100V or 2,000VA output. The winding is tapped at 100V so that the autotransformer functions as a 200V-to-100V stepdown transformer. While this is an acceptable transformer connection, its application is rather limited because of the absence of isolation between input and output circuits. Get price

Flyback Converter Design

Hence if the load current increases, after the circuit has settled down, the duty cycle will remain unchanged, but the primary and secondary ripple currents will not ramp all the way down to zero. So instead of having a triangular waveform starting from zero, the primary current will have a front end vertical step from zero to a certain value, then ramp from there. Get price
