NBRA-659C Brake chopper IP00

Brake chopper is an electrical switch that is mainly used to control occasions where the mechanical load is heavy and the braking speed is required to be very fast. Specifically, when the load recharges energy to the DC chain, the brake chopper can use the brake chopper and brake resistor to control the voltage of the DC chain. For example, an excited motor with a passive towed load behaves like a generator, converting kinetic energy into electrical energy and sending it to the DC end. This method of matching the resistance and making the resistance consume energy when braking is called resistance braking.

The brake chopper works as an electronic switch that limits the DC bus voltage by switching the brake energy to a resistor. In this resistor, the braking energy is converted into heat energy. The chopper is automatically activated when the actual DC bus voltage exceeds the specified level (depending on the nominal voltage of the variable frequency drive).

There are many types and applications of brake choppers, for example, Braking choppers is a circuit installed at the DC end of the inverter. When the load recharges energy to the DC chain, the brake chopper and brake resistance can be used to control the voltage of the DC chain
