If someone told you that the solid-state power recovery controller is a perpetual motion machine, what would be your reaction?
Explain whether the solid state power recovery controller is a perpetual motion machine or not.
Answer to Problem 1SQ
No, the solid state power recovery controller is not a perpetual motion machine.
Explanation of Solution
A machine which provides an output without an input energy source is known as perpetual motion machine. The energy is neither created nor destroyed. Therefore, there will be no losses in this system.
In the solid state power recovery controller machine, there should be some energy applied to keep the machine in motion. It includes losses such as copper loss, iron loss, friction, and windage loss. Due to these losses, the output is lesser than the input. Therefore, the solid state recovery controller is not a perpetual motion machine.
Conclusion:
Thus, the solid state power recovery controller is not a perpetual motion machine.
