Applications & Selection
Power Switching Across Applications
01 · AI Server Intermediate-Bus Power
Relevant Devices: Silicon MOSFETs · GaN FETsConverting a 48 V-class bus for accelerator boards emphasizes high current, conduction loss, and board-level heat removal. Compare silicon MOSFET on-resistance at operating temperature, gate charge, and switching loss; for high-frequency designs, also check GaN drive and layout requirements.
02 · EV Traction Inverters
Relevant Devices: SiC MOSFET Modules · IGBT ModulesA traction inverter converts battery DC into three-phase motor power. Match the modules to DC-bus voltage, peak phase current, and the drive cycle, then compare SiC and IGBT losses, short-circuit capability, and cooling requirements.
03 · Industrial Variable-Frequency & Servo Drives
Relevant Devices: IGBTs · Power ModulesMotor starts, braking, and continuous operation impose overloads and repeated thermal cycles. Check IGBT on-state voltage, turn-off loss, and module cooling against DC-bus voltage, PWM frequency, and the load cycle.
04 · Solar String Inverters
Relevant Devices: SiC MOSFETs · IGBTsThe MPPT DC/DC and grid-tied DC/AC stages have different blocking-voltage and switching requirements. Establish device voltage ratings from the system voltage and two- or three-level topology before comparing SiC and IGBT losses and cooling under the intended operating conditions.
05 · Bidirectional Energy Storage Conversion
Relevant Devices: SiC Power Modules · IGBT Power ModulesA storage converter operates in both charging and discharging directions while battery voltage varies with state of charge. Select modules for the full voltage range, then check losses in both directions, short-term overloads, and thermal cycling.
