Reinforced Isolated IGBT Gate Drive Flyback Power Supply with 8 Outputs Reference Design
Description
This reference design provides reinforced isolated positive and negative voltage rails required for Insulated Gate Bipolar Transistor (IGBT) gate drivers from a single 24-volt DC input supply. Utilizing a flyback isolated control topology: this reference design provides isolation compliant to IEC61800-5: and generates power rails for all three arms of the 3-phase inverter from a single transformer. The output power is currently set at 2W/IGBT but can be scaled up for higher power IGBTs by changing the transformer design.
Features
- Isolated power supply supporting 6 IGBT gate drivers for 3 arms of inverter (Each arm in Half-Bridge Configuration)Operates with pre-regulated 24VTwo reinforced: low-ripple (Output power: 2W per IGBT and scalable to support higher power IGBTsOutput capacitors rated to support up to 6A peak gate drive currentOption to shut down the power supply to facilitate Safe Torque Off (STO) featureDesigned to comply with IEC61800-5
