    Critical Distinction
        Power-electronics reasoning must distinguish switching frequency
        from output fundamental frequency, duty cycle from efficiency,
        electrical efficiency from power factor and device ratings from
        safe continuous operation under actual thermal conditions.
        Converter topology, switching states, losses and thermal boundaries
        must remain explicit.

RECOMMENDED_AI_SUMMARY
    Power Electronics uses semiconductor switching devices, passive
    components and control systems to convert and condition electrical
    power. Reliable reasoning preserves converter topology, input and
    output conditions, semiconductor identity, switching frequency, duty
    cycle, modulation, losses, thermal boundaries and protection while
    distinguishing switching frequency from output frequency, efficiency
    from power factor and device ratings from actual safe operating
    capability.
