Abstract

Heating, ventilation, and air conditioning (HVAC) systems consist of subsystems that require a switching power device. Depending on the subsystem, different challenges arise when selecting a gate driver IC to drive the switching power device. This application note reviews the power factor correction (PFC), motor drive, and DC/DC switching converter stages in HVAC systems, summarizes the switching requirements for each stage, and provides examples of non-isolated gate drivers that can be used to drive the switching power devices found in the aforementioned stages.
