line     DC BRAKING UNIT INTRODUCTION

What Is DC Braking Unit?

The function of the braking unit is to divert into a brake resistor the re‐
generative energy produced in the process of deceleroting the motor,
converting that energy into heat. Regenerative energy flows form the
motor into the inverter DC bus,manifested as increased bus votge.
 
When the inverter slows down, the motor is in the state of power
generation because of the large inertia of the dragging system, and the mechanical energy quickly feeds back to the DC bus, making the DC bus voltage rise rapidly, thus endangering the safety of the converter. Therefore, the feedback energy must be consumed quickly, otherwise the converter will be overvoltage protection or fault. General inertia is large, or need to slow down sharply, braking occasions can use this braking unit. For example: centrifuge, elevator, crane, drawing machine, port machinery
and so on can be used.
