The IT servers for a medium-sized company need to be protected from grid failures (e.g. blackout) and thus is powered through an uninterruptable power supply (UPS) unit. The UPS consists of a 3- phase diode rectifier powering the dc bus, which then splits between a 3-phase inverter unit and a battery energy storage system (BESS). UPS parameters are given in Table B2 and a general schematic is shown in Figure B2. Assuming that the inverter and BESS pull a combined constant current, IDC, from the dc bus, draw the approximate waveforms over one full ac cycle for: (i) the three ac line voltages, (ii) the three ac currents, and (iii) the total dc bus voltage. Explain how the single-phase inverter operates and draw an approximate waveform of the load-side ac voltage. Comment on the chosen switching frequency for the inverter. Choose a dc/dc converter topology for the BESS. Draw the converter diagram for your chosen topology and justify each of your design choices. Estimate the battery…

An Engineer is tasked with implementing a lighting circuit with a 24 V battery. Part of the task included making sure power was conserved, e.g., ensuring the light stays off during daytime. The engineer selects a generic phototransistor to detect enough ambient light when present. The circuit below contains two transistors in series Q1, & Q2. This means that for the 35-Watt lamp (load) to work both transistors must be “ON” (or conducting), else the lamp is “OFF” (no current flows). Transistor Q1 is turned on by actuating the switch “SW1”. Transistor Q2 is turned on by the phototransistor Q4. The circuit is powered by a 24V Battery. Figure 1 shows the control circuit schematic and the simplified (equivalent) logic gate version of the circuit. (Hint: calculate your answer using Ohms law.)
