Title:
PULSE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/139636
Kind Code:
A1
Abstract:
A pulse control device 10 comprises: a switch output unit 100 which generates a pulse output voltage Vo from a direct-current input voltage Vi and supplies the pulse output voltage Vo to a load (such as a relay coil 21 of a mechanical relay 20); a low-pass filter unit 300 which receives a feedback input of the pulse output voltage Vo and generates a feedback voltage Vfb; and an output feedback control unit 200 which receives an input of the feedback voltage Vfb and controls the switch output unit 100 so that an average value of the pulse output voltage Vo becomes constant. The low-pass filter unit 300 may be configured without a coil.
