2- Calculate the values of Ro, Xo, Reg1 and Xeg1 of the equivalent circuit of a 1-ph, 4KVA, 200/400V, 50HZ transformer of which the following are test results: open-circuit: 200V, 0.7A and 70W on low-voltage (primary) side. Short-circuit: 15V, 10A and 80W on high-voltage (secondary) side. [571, 330, 0.2 and 0.3172]

Find the following : 1.Ripple Voltage (vpp) 2. Zero-to peak ripple(Vop) 3.secondary winding of the transformer high line and low line

The IT servers for a medium-sized company need to be protected fromgrid failures (e.g. blackout) and thus is powered through anuninterruptable power supply (UPS) unit. The UPS consists of a 3-phase diode rectifier powering the dc bus, which then splits between a3-phase inverter unit and a battery energy storage system (BESS). UPSparameters are given in Table B2 and a general schematic is shown inFigure B2.a) Assuming that the inverter and BESS pull a combined constant current,IDC, from the dc bus, draw the approximate waveforms over one full accycle for: (i) the three ac line voltages, (ii) the three ac currents, and(iii) the total dc bus voltage.
