When an engineer measured the outputs of his solar panels, he saw that he obtained a DC voltage varying between 200V and 600V depending on the environmental conditions. This engineer connected this variable voltage from solar panels to the input of a buck-boost type DC-DC converter. Which of the following statements about this situation is false? a) In case the output voltage is desired to be kept constant at 400V, Duty (operation ratio-D) will change between 2/3 and 2/5. b) If the frequency of the switch in the circuit is 10 kHz, the coil value is L-2mH and the output voltage is 400V, if the limit value of the coil current is 5A, the voltage received from the panels (converter input) is 400V. c) None d) If the output voltage is to be kept constant at 300V and the Duty (operating ratio D) is at its maximum, the ratio of the output current to the input current is 2/3. e) If a load of R=10 ohm is connected to the output when the output voltage is desired to be kept constant at 400V, the current to be drawn from the solar panels (input) will be approximately 16 A, the minimum current.

You are designing a power supply for a 100 W high-quality audio amplifier that will drive an 8 Ohm speaker. The datasheet says you need approximately a 75 V Vcc rail to properly supply the transistor power stage. To get the excellent performance you expect, you aim for 1% ripple, and choose a design that minimizes the amount of capacitance required to reduce cost.

Without writing or drawing tools to lean on, you must use words, not equations, graphs or schematics in your explanation. The current in a differential pair of transistors swings between the two sides of the transistor pair as the input voltage swings between the inputs. The output voltages of course follow the current inversely. Is this swing of current related to one of the chief advantages of differential operation, the elimination of common mode signals? Keep in mind, there is a restricted range of allowed current (and voltage) swing to keep the amplifier operating in a linear way
