In Dhaka city during the month of May, a 20W rated solar panel supplies 15W of power at an output voltage of 15V & an output current of 1A. But during the month of December, the same solar panel supplies 8.5W of power at an output voltage of 10.5V & an output current of 0.81A. The solar panel is used to charge a 12V battery. Practically, for charging a 12V battery we need to supply 13V. In the month of May, the user will need a DC-DC converter (Buck) to charge the battery. 2. What will be the duty cycle? 3. Assuming that the converter is 100% efficient, what will be the input current to the battery? 4. In the month of December, the user will need a different DC-DC converter (Boost) to charge the battery. 5. What will be the duty cycle? 6. Assuming that the converter is 100% efficient, what will be the input current to the battery?
Power Amplifier
The power amplifier is an electronic amplifier designed to maximize the signal strength of a given input. The input signal strength is enhanced to a high enough level to drive output devices such as speakers, headphones, RF (Radio frequency) transmitters, etc. Unlike voltage / current amplifiers, the power amplifier is designed to drive core loads directly and is used as a storage block in the amplifier series.
Maximum Efficiency Criterion
In every field of engineering, there is a tremendous use of the machine and all those machines are equipped for their popular work efficiency so it very much important for operation engineers to monitor the efficiency of the machine, planning engineers to check out the efficiency of the machine before installing the machine and design engineers to design machine for higher efficiency than and then the utility will procure their products that will ultimately lead to profit and loss of the company. It indicates the importance of efficiency right from the initial stage as manufacturing units, intermediate stage as planning coordinators, and end-users stage as a utility.
