Operating frequency of power MOSFET is higher than that of power BJT. Justify the statement.
Last answer:
Power MOSFET have high turning on and turning off capability high switching speed of MOSFET is due to the high rate of change of drain voltage. The switching losses of power MOSFET ... lower frequency. Hence, operating frequency of power MOSFET is higher than that of power BJT.
