AI 生成的摘要: Power Factor Correction (PFC) improves electrical power efficiency by optimizing the phase relationship between voltage and current. Passive PFC uses passive components like capacitors and inductors to filter harmonics, suitable for low-power applications under 100W but with lower efficiency and larger size. Active PFC employs switching converters to achieve power factors above 90%, reducing energy loss and harmonic distortion, ideal for high-power applications such as industrial motors, data centers, and EV chargers. Interleaved PFC uses dual IGBTs to enhance efficiency further by minimizing current ripple and improving power stability in demanding environments.

AI 生成的摘要: The TO-247plus package differs from the TO-247 mainly by including screw holes while maintaining similar external dimensions and pin pitch, allowing easy board design compatibility. Heat dissipation is critical for IGBTs due to power generation; proper mounting torque (20-100 N) ensures stable thermal contact without damaging the device. Applying thermal grease significantly improves heat conduction by reducing thermal resistance by 1.8 times. The TO-247plus package offers better heat dissipation than TO-247 due to a larger chip mounting frame. Proper device handling during heatsink mounting prevents damage such as resin chipping or internal cracking.

AI 生成的摘要: When connecting IGBTs in parallel, current unbalance occurs due to differences in VCE(sat) and parasitic resistances in the wiring and board. This unbalance affects device loss and switching behavior. Minimizing VCE(sat) variation by using devices from the same production lot and designing symmetrical layouts reduces unbalance. Gate driver emitter-sense wiring must also be symmetrical to ensure equal gate voltages. Temperature dependence of VCE(sat) influences current sharing, with positive temperature dependence improving stability.

AI 生成的摘要: The document defines absolute maximum ratings for IGBTs, including voltage, current, power dissipation, and temperature limits to ensure safe operation.
