A brake controller and an elevator system including the brake controller are disclosed. The brake controller includes a DC link for supplying power, the DC link including a positive DC link rail and a negative DC link rail; output terminals for connecting to a magnetizing coil of an electromagnetic brake; a current path established between the DC link and the output terminals for conducting DC link power to the magnetizing coil; and two solid-state switches fitted into the current path. Both solid-state switches are configured to adjust output terminal voltage by modulating the DC link voltage.
