# How much is the minimum braking time of the 11 kw inverter?

How much is the minimum braking time of the 11 kw inverter?

A braking resistor is a carrier used to heat the regenerative energy of an electric motor in a heat energy manner. When selecting the braking resistance, two important parameters should be considered: resistance and power capacity. As for the material, according to the needs of the choice of reasonable performance, stability of high resistance,

What is called braking utilization is the percentage of deceleration divided by the deceleration period. For example, 100% of the power is consumed within 5 seconds of the deceleration, and the braking resistance takes 90 seconds to complete the heat.

When the DC bus voltage is greater than the braking resistance action, the voltage quasi position, the braking resistor energy consumption.

The selection of the resistance value of the brake resistance shall satisfy a basic condition: the current flowing through the resistor shall be less than the maximum current value allowed by the resistor Ic.

That is, R<760/ Ic (760VDC is generally defined as the maximum value of converter bus voltage). For example, 11KW inverter rated current of about 22A, then R should be less than 34.5 ou.
