Title:
POWER MODULE, VOLTAGE-SHARING APPARATUS AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/267393
Kind Code:
A1
Abstract:
The present application provides a power module, a voltage-sharing apparatus and an electronic device. The power module is a first power module. The first power module is configured with a first input port, a second input port, a first output port, a second output port, and a first communication port. The first power module comprises a power management circuit. In the present application, when a fault is detected by the power management circuit, a first difference of voltage drop of change is determined, a first voltage compensation signal or a second voltage compensation signal is generated according to the first difference and then is sent to a second power module, such that the second power module increases the voltage according to the first voltage compensation signal or the second voltage compensation signal, and the second power module is controlled to actively increase the output voltage, such that the total voltage in a series system does not change, and voltage backlash is avoided while the voltage redundancy design of the series system is realized.
