A MOSFET transistor is being used as a converter switch in a 100v system. It is switching at 50 KHz and has a linear transition time of 3us. The full load current is 40 amps.
- How much average power is being wasted due to switching?
- If this is the only loss mechanism, what is the system efficiency?
- What transition times would be needed to achieve an efficiency of 90%?
- If the frequency is doubled, describe the change in efficiency?
