If the control nickname from the power line is demodulated, the dc signal of the DC 11 200841573 regulator unit is adjusted or adjusted according to the control signal. power supply. The digital power controller of the model Si825〇, as a pulse width modulation controller, includes a digital input/output interface U/gital peripherals), so it can be connected to the digital processing unit of the power line communication unit, and it is provided with power idle. Mode (idle m〇de) and stop content. ^ mode (stop mode), in conjunction with the instruction manual of the controller, the digital processing unit (53) of the power line communication unit (5G) can be idle or stopped according to the first digital input and output interface of the control signal (33)模向令· A 社丄._ In addition, the third digit output interface (531) of the digital processing unit (5 3) of the power line communication unit (5 〇) can also be connected to the power factor correction of the AC/DC conversion unit (10) The second digital output interface of the controller (25) is used to demodulate the control signal transmitted from the power line, and then raise or lower the DC power output of the DC voltage regulator unit according to the control signal. Since the pulse width modulation controller (33) obtains the output primary side current value and the feedback voltage value of the direct power source, the first pulse width modulation controller (33) can further apply the current value and voltage.
