The key difference between an IGBT and an IGBT Bridge lies in their structure and functionality. Here’s a breakdown:

1. IGBT (Insulated Gate Bipolar Transistor)

• Definition: A single semiconductor device that acts as a switch for high-power applications.
• Function:
  • Can switch ON/OFF high voltage and current (e.g., 100A, 1600V).
  • Combines the fast switching of a MOSFET with the high current handling of a BJT.
• Applications:
  • Used in inverters, motor drives, power supplies, and UPS systems.
  • Typically requires external circuitry for complex operations (e.g., AC conversion).

2. IGBT Bridge

• Definition: A circuit configuration using multiple IGBTs (usually 4 or 6) arranged in a bridge topology (H-bridge, 3-phase bridge).
• Function:
  • Enables bidirectional power flow and AC/DC conversion.
  • Used for full-wave rectification, inversion, or motor control.
  • Commonly controlled using PWM signals for variable output.
• Applications:
  • Motor drives (e.g., servo & induction motors).
  • Solar/wind inverters.
  • Industrial welding machines.
  • Electric vehicle powertrains.

Key Differences

Summary

• An IGBT is a single switching device, while an IGBT Bridge is a pre-configured circuit using multiple IGBTs for advanced power control.
• IGBT Bridges are used where AC/DC conversion, motor control, or bidirectional power flow is needed.
• A 100A 1600V IGBT Bridge would typically be a module (like SEMIKRON or Infineon) with built-in IGBTs, diodes, and protection circuits.

2. Key Components

• IGBTs (100A 1600V):
  • Six IGBTs (e.g., Infineon FF100R16XT4) rated for 100A continuous current and 1600V blocking voltage.
• Anti-parallel Diodes:
  • Fast-recovery diodes (integrated in most IGBT modules) for freewheeling current.
• Gate Drivers:
  • Isolated drivers (e.g., Infineon 1ED020I12-F2) to switch IGBTs safely.

• PWM Controller:
  • Generates switching signals (e.g., Microcontroller or DSP like TI C2000).

3. How It Works

1. DC to AC Conversion:
   • The IGBTs are switched in pairs (PWM-controlled) to generate 3-phase AC output.
   • Example switching sequence for Phase U:
     • IGBT1 ON → Positive voltage.
     • IGBT4 ON → Negative voltage.
     • Dead-time prevents shoot-through.
2. Output Waveform:
   • By modulating PWM duty cycles, a sinusoidal AC waveform is synthesized.
   • Frequency and voltage are adjustable (e.g., 0-400Hz, 0-480V AC).
3. Protection Features:
   • Overcurrent protection (desaturation detection).
   • Temperature monitoring (NTC thermistor).
   • Snubber circuits to reduce voltage spikes.

4. Example Applications

• Industrial Motor Drives:
  • Controls 3-phase induction/Servo motors (e.g., 10-100HP).
• Solar Inverters:
  • Converts 600-1000V DC from solar panels to 380V AC.
• Electric Vehicle (EV) Powertrains:
  • Drives traction motors (e.g., Tesla’s inverter uses similar IGBT bridges).
