Frequency Inverter Braking Resistor

The lower the ohmic value the higher the power.

Frequency inverter braking resistor.

The designer calculates the power rating of the resistor to stay under the temperature limits during braking. The dc link capacitance of any inverter drive can itself absorb 3 5 of the regenerated power. The ohmic value sets the rate at which we put the energy into the resistor the braking power. And the stop frequency.

The rate of braking is determined by how fast the energy is put into the braking resistor. Therefore a high load capacity and long life are very important. Braking resistors in variable frequency drive vfd increase the braking torque capability producing faster and more controlled braking. The braking resistor dissipates regenerated power to keep the bus voltage from exceeding the rated limit of the drive.

Synchronous speed set by the output frequency of the drive an overhauling load condition a braking resistor is required. The dc link capacitance of any inverter drive can itself absorb 3 5 of the regenerated power. Average regenerative energy resistance capacity of braking resistor. Determines the dbr peak power.

It is important to correctly size a braking resistor. To compensate this the resistor must be bigger or use a heat sink. During braking operation the brake resistor converts a large amount of regenerative energy into thermal energy. Brake resistor size 4 33r 500w.
