A brake chopper is a high-speed semiconductor switch (IGBT or MOSFET) integrated into a VFI system to manage regenerative energy. When the DC bus voltage exceeds a predefined threshold, the brake chopper activates, diverting excess energy through a high-power resistor. This process prevents overvoltage tripping, protects sensitive components, and ensures continuous operation.
Dynamic Braking Unit: A dynamic braking unit is a subsystem that combines the brake chopper with a high-wattage resistor. It specializes in rapid energy absorption during motor deceleration, converting kinetic energy into heat while maintaining precise control over the braking process.
