Abstract
An energy supply device includes: a transformer with a first winding; a power switching device; a feedback device; and a voltage supply device for providing supply voltage for the feedback device. The power switching device is coupled to the first winding and connects through periodically by a control signal generated by the feedback device. The feedback device includes a first switching element for interrupting the control signal when a shut-down signal occurs.
Claims14
An energy supply device, comprising:
- a transformer with a first winding;
- a power switching device;
- a feedback device;
- and
- a voltage supply device configured to provide supply voltage for the feedback device,
- wherein the power switching device is coupled to the first winding and configured to connect through periodically by a control signal generated by the feedback device,
- wherein the feedback device comprises a first switching element configured to interrupt the control signal when a shut-down signal occurs, and
- wherein the feedback device comprises a second switching element configured to interrupt the supply voltage for the feedback device when the shut-down signal occurs.

A method of switching off an energy supply device, comprising:
- providing the energy supply device, which comprises a power switching device, an emergency stop switch, a feedback device and a voltage supply device configured to provide supply voltage for the feedback device;
- and
- periodically connecting through the power switching device by a control signal generated by the feedback device,
- wherein, when the emergency stop switch is actuated, one or more switching elements are opened and thereby a generation of the control signal is prevented or the control signal is blocked,
- wherein the control signal is blocked with one switching element of the one or more switching elements when a shut-down signal generated by the emergency stop switch occurs, and
- wherein the supply voltage for the feedback device is interrupted with another switching element of the one or more switching elements when a shut-down signal generated by the emergency stop switch occurs.
