    Abstract: Aparato de frenado (1) para un ascensor, el cual comprende: - un aparato (3) de frenado dinámico, para frenar una máquina eléctrica (4) con frenado dinámico, - una entrada para una señal de control (5, 7) del aparato de frenado, - un controlador (8) para controlar el aparato (3) de frenado dinámico como una respuesta a la señal de control (5, 7) antes mencionada del aparato de frenado, en donde el controlador (8) comprende los modos de control (10, 11, 12, 13) para controlar el aparato (3) de frenado dinámico de acuerdo con el modo de control a utilizar en cualquier momento dado, caracterizado por que - el controlador (8) se dispone para activar el aparato (3) de frenado dinámico después de un retardo de activación ajustado (15) de frenado dinámico tras recibir una señal de parada de emergencia (7), y - por que un freno de maquinaria (2) se dispone para ser activado después de un determinado retardo de activación (16) del frenado de maquinaria tras recibir la señal de parada de emergencia (7), en donde el retardo de activación (15) del frenado dinámico se ajusta para ser más largo que el retardo de activación (16) del frenado de maquinaria.

    Abstract: The invention relates to an elevator system having a braking apparatus for dynamic braking which is controlled by a control signal of a controller, the controller (8) having control modes (10, 11, 12, 13) for controlling said apparatus (3). The invention is based on that the controller (8) is arranged to switch into a prevention mode (11) of dynamic braking when the controller (8) receives a parameter that refers to prevention mode of dynamic braking from a user interface (18), and that the controller is arranged to switch from the prevention mode of dynamic braking into a normal mode (12) of dynamic braking after it detects specific situations.

    Abstract: DC/DC bridge for controlling a direct-current load (M1), which bridge is provided with controllable semiconductor switches (S11 - S14, S21 - S26) and with a control unit (BC1). The bridge comprises two bridge sections (B11, B12), at least the first bridge section (B11) of which is controlled with pulse-width modulation (PWM) to regulate the current magnitude, and which bridge comprises a determination of the current of the direct-current load (M1). The second bridge section (B12) conducts direct current when the determined value (2) of the current of the direct- current load differs from zero by more than the limit value (1) of the current.
