Which consequence results when thermal runaway occurs within a densely-packed, high-voltage DC-DC converter system?

A)Cascading component failures initiate
B)System efficiency remains constant
C)Controlled shutdown becomes immediate
D)Stable temperature equilibrium develops

💡 Explanation

Cascading component failures occur in DC-DC converters experiencing thermal runaway due to positive feedback. The increased heat triggers the Arrhenius equation, causing accelerated degradation of adjacent components. Therefore, failure cascades downstream rather than equilibrium occurring, because cooling systems cannot remove heat quickly enough.
