Abstract

The present disclosure relates to an elevator technology, and in particular to a device and method for brake control. According to one aspect of the present disclosure, there is provided a device for brake control. The device comprises a first branch circuit and a second branch circuit connected in parallel with the first branch circuit. The first branch circuit and the second branch circuit comprise a first brake coil and a first switching element connected in series and a second brake coil and a second switching element connected in series, respectively. The device further comprises a third switching element connected between a power supply and the first branch circuit and the second branch circuit, which is configured to connect or disconnect the power supply with the first branch circuit and the second branch circuit in response to the state of an elevator safety chain. In the device, when the power supply is connected with the first branch circuit and the second branch circuit, the supply of power from the power supply to the first brake coil and the supply of power from the power supply to the second brake coil are controlled by the first switching element and the second switching element, respectively. In particular, control signals for the first switching element and the second switching element comprise a pulse width modulation signal.
