Which outcome occurs when parasitic capacitance increases within a high-frequency rectifier circuit?

A)Increased switching current losses occur
B)Improved power factor get achieved
C)Reduced electromagnetic interference happens
D)Enhanced circuit efficiency becomes observed

💡 Explanation

Increased parasitic capacitance leads to increased capacitive reactance and therefore larger switching currents during transistor transitions because of the MOSFET gate capacitance charging and discharging cycle. Therefore, higher switching losses manifest physically, rather than improved efficiency which would occur with lower capacitance.
