Title:
SINGLE-POWER-SUPPLY CIRCUIT AND POWER SUPPLY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/177197
Kind Code:
A1
Abstract:
A single-power-supply circuit and a power supply system. A power-supply circuit comprises: a power supply (10), an energy-storage capacitor (30) which is in parallel connection with a load (20), a control unit (40), a signal processing unit (50), a main circuit (60) and a charging circuit (70). The power supply (10) is connected to the load (20) through the main circuit (60) and the charging circuit (70) respectively; the resistance of the charging circuit (70) is greater than that of the main circuit (60); the control unit (40) is connected to the main circuit (60) through the signal processing unit (50); and the signal processing unit (50) is configured to convert a control signal sent by the control unit (40) into a driving signal of the main circuit (60). When the power supply (10) is switched on to supply power to the load (20), the power supply (10) charges the energy-storage capacitor (30) through the charging circuit (70); and after the power supply (10) charges the energy-storage capacitor (30), the control unit (40) drives the main circuit (60) to be communicated, so that the power supply (10) supplies power to the load (20) through the main circuit (60).
