If your IR2110 circuit isn't behaving as expected in Proteus, consider these common checks:
Although some components exist in older libraries, a dedicated, updated Proteus library ( .LIB and .IDX files) provides an accurate SPICE simulation model. Without this, your high-side MOSFET will not switch correctly in simulation, as the bootstrap mechanism ( VBcap V sub cap B VScap V sub cap S ) requires accurate voltage calculation. ir2110 library for proteus 8 upd
Third, the (the hardest part): Proteus 8 uses SPICE and VSM (Virtual System Modelling). Arjun didn’t have the actual silicon code, so he downloaded a public .MODEL file from a university archive. He attached it to the component using the PRIMITIVE = ANALOG property. If your IR2110 circuit isn't behaving as expected
"Classic," Arjun sighed. "The bootstrap hasn't charged." Arjun didn’t have the actual silicon code, so
: Completely close and reopen Proteus to refresh the component list. 4. Simulation Note
As of the latest releases, Proteus is actively expanding its library of power electronics components. Recent updates have added models for various Intersil transistors and edge controllers from International Rectifier. While the official library still lacks a native IR2110 model, the growing demand for power electronics simulation means that component libraries are becoming more comprehensive with each update.
Because the IR2110 relies heavily on transient bootstrap charging, standard digital simulation settings in Proteus may fail or throw errors. : Place a high-quality capacitor between pin 6 ( VBcap V sub cap B ) and pin 5 ( Vscap V sub s
