← TechnologyWhich risk seriously increases when impedance drops unexpectedly in a resonant inverter circuit?
A)Increased MOSFET current spiking✓
B)Decreased transformer core saturation
C)Harmonic distortion cancellation failure
D)Phase-locked loop frequency drifting
💡 Explanation
Increased MOSFET current spiking is a risk because diminished impedance in a resonant inverter circuit increases current flow through the MOSFETs via Ohm's Law. Therefore, MOSFET failure risk rises, rather than core saturation being lessened or PLL behaviour being affected.
