Title:
AEROSPACE LOW-VOLTAGE BUCK ANTI-INTERFERENCE AND DELAY STARTING CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2023/077920
Kind Code:
A1
Abstract:
The present invention relates to an aerospace low-voltage BUCK anti-interference and delay starting circuit in the technical field of aerospace power sources. The circuit comprises: an input bus (1), a low-voltage BUCK circuit (2), an isolation and filtering circuit (3) and an enabling-end delay starting circuit (4), wherein the input bus (1) is used for supplying power to the low-voltage BUCK circuit (2), the isolation and filtering circuit (3) and the enabling-end delay starting circuit (4); the low-voltage BUCK circuit (2) is used for supplying power to a load; the isolation and filtering circuit (3) is used for isolating a power circuit and a control circuit in the low-voltage BUCK circuit (2), and performing filtering; and the enabling-end delay starting circuit (4) is used for controlling the starting or disconnection time of the low-voltage BUCK circuit (2). By means of the present invention, the on-load characteristic, starting characteristic and power-off characteristic of a low-voltage BUCK circuit can be enhanced, and power-on and power-off are made monotonic.
