Abstract

The invention relates to a wide-range input power supply structure which at least comprises a first topological power supply circuit and a second topological power supply circuit, an input voltage isconnected to one ends of the first topological power supply circuit and the second topological power supply circuit, and the other ends are connected with a load. The second topological power supply is provided with a delay module capable of delaying an input power supply to enable the first power supply circuit to complete parameter identification of the input power supply, and the second topological power supply circuit can delay output when powered on. Under the condition that the second topological power supply circuit does not detect the output voltage of the first topological power supply within the delay time, the second topological power supply circuit is configured to supply power to the load.

Description

technical field [0001] The invention relates to the technical field of power supply, in particular to a wide-range input power supply structure. Background technique [0002] Input voltage is one of the key parameters of power supply design. In a topology, different input voltages have different power supply characteristics, which will be manifested in different aspects, such as output linear adjustment rate, dynamic characteristics, thermal characteristics, etc. It is more obvious in wide-range input power supply, which increases the difficulty of design. Engineers need to balance the performance, volume, heat, and cost of the power supply. For some ultra-low voltage inputs, there may be a problem of not being able to start. The Chinese patent document with the publication number CN105006960B discloses a low-voltage start-up switching power supply, which relates to a low-voltage start-up switching power supply. The invention solves the problems of large circuit volume and ...
