Title:
BIDIRECTIONAL ISOLATED DIGITAL DCDC POWER SUPPLY AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2019/080080
Kind Code:
A1
Abstract:
A bidirectional isolated digital DCDC power supply and a control method, the power supply comprising an input side (102), an output side (104) isolated from the input side (102), a feedback circuit (106) and an isolated pulse width modulator (112) connected to the input side (102), a photocoupler (108) connected to the feedback circuit (106), and a digital signal processor (110) connected to the optocoupler (108) and the isolated pulse width modulator (112); the feedback circuit (106) is configured to acquire an output voltage error of the input side (102); the photocoupler (108) is configured to send the output voltage error to the digital signal processor (110); the digital signal processor (110) is configured to acquire a voltage feedback parameter according to the output voltage error; the isolated pulse width modulator (112) is configured to adjust, according to the voltage feedback parameter, an output voltage of the input side (102), thereby improving reliability of the power supply.
