17. For the set of input waveforms in Figure 3–83, determine the output for the gate shown anddraw the timing diagram.?   1.  Repeat Problem 17 for an exclusive-OR gate.?

There are three logic gates. Logic gate A draws 3.6μA when the output is HIGH and 2μA when the output is LOW. Logic gate B draws 2.8μA when the output is HIGH and 1.5μA when the output is LOW. Logic gate C draws 1μA when the output is HIGH and 2μA when the output is LOW. Analyse which logic gate you would recommend for best power performance given operating voltage of 5V and 50% duty cycle. Associate your recommendation with appropriate steps and calculations.

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…
