Science

Within a pulsed laser power supply relying on capacitor discharge, which failure mode occurs after exceeding maximum permissible equivalent series inductance (ESL)?

A)Incomplete energy transfer to lasing medium
B)Thermal runaway propagates within capacitor
C)Dielectric breakdown of insulating components
D)Increased impedance matches lower voltages

💡 Explanation

Incomplete energy transfer results, because parasitic inductance opposes rapid current changes, thereby limiting pulse power due to inductive impedance. Therefore, rise time suffers rather than dielectric breakdown, because overvoltage conditions are indirectly affected.
