When selecting an IGBT model, consider these key parameters: Operating voltage (V_CES) should be 1.2-1.5 times the maximum system voltage; current (I_C) should be selected based on load current and thermal conditions, typically with a 20%-30% margin; switching frequency affects loss distribution, and high-frequency applications should choose high-speed switching IGBTs. Please refer to our selection guide or contact technical support for professional recommendations.

SiC MOSFET offers several advantages over IGBT: ① Lower switching losses — SiC MOSFET is a majority carrier device with no tail current, reducing switching losses by over 70%; ② Higher switching frequency — can reach 100kHz+, significantly reducing magnetic component size; ③ Higher operating temperature — junction temperature up to 175°C or even 200°C, with lower cooling requirements; ④ Higher efficiency — especially at light loads. However, cost is higher, and advantages are more pronounced in high-voltage, high-power applications.

Power module installation notes: ① Heatsink flatness must be within 0.05mm, surface roughness Ra≤1.6μm; ② Thermal grease must be applied evenly, thickness controlled at 50-100μm; ③ Screw tightening torque must strictly follow specifications, using cross-diagonal step-by-step tightening; ④ Avoid bending or torsional stress on the module; ⑤ Thermal resistance testing is recommended after installation to verify heat dissipation.
