The is a high-voltage, high-speed power MOSFET and IGBT driver from Infineon (formerly International Rectifier). It features independent high and low side referenced output channels, making it essential for half-bridge, full-bridge, and buck converter topologies.

reaches the necessary level (often 10V–15V) to minimize heat dissipation. Conclusion

The IR2110 is a high-speed, high-voltage power MOSFET and IGBT driver with independent high- and low-side output channels. While standard versions of Proteus may not include every specific gate driver in their default library, third-party allow engineers to simulate complex power electronics like H-bridges, motor controllers, and inverters with high accuracy. Key Features of the IR2110 Library Component

Often an Arduino UNO or PIC to generate the PWM signals for the HIN and LIN pins.

Search for "IR2110" in the "Pick Devices" (P) window to confirm the model is active. 5. Circuit Configuration & Bootstrapping

Connect a (paralleled with a 0.1uF ceramic capacitor for noise) between VB and VS .

If the simulation runs extremely slowly or freezes:

Place DC voltmeters across the bootstrap cap to see charging waveform. Place current probes on the load to visualize switching transients.

This is not accurate but works for logic verification.

Custom user-created models sometimes outperform official ones. One user noted that the official IR2110 model "ran incredibly s-l-o-w-l-y, or not at all," and subsequently created an alternative model for faster simulation.

Since the standard Proteus library may lack the SPICE model for the IR2110, you must manually add the custom library files ( .LIB and .IDX ). Step 1: Download the Library Files
