VFD Braking Resistor Calculation: A Technical Guide to Dynamic Sizing

Key Takeaways: VFD braking resistor calculation requires determining two critical values: minimum resistance (Ohms) based on DC bus voltage, and power rating (Watts) based on the braking duty cycle. Undersizing the resistor resistance can destroy the VFD’s braking chopper, while undersizing the power rating leads to thermal failure. Understanding the load’s duty cycle—whether it’s a […]
