Embodiment Construction

[0015] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0016] Such as figure 1 as shown, figure 1 It is a structural schematic diagram of the large-current fast-switching high-transient-response power supply of the present invention.

[0017] The high-current fast-change high-transient-response power supply of the present invention includes a lighting module connected to each other, a timing control module and a power management function module.

[0018] Its working principle is: the lighting module converts the DC power supply of the previous stage to DC-DC to obtain a low-voltage DC power supply, and outputs it to the driver board. The voltage feedback loop directly feeds back the voltage signal from the driver board to the pulse width modulator of the lighting module to realize The remote feedback of the rear stage is adopted, the internal feedback loop is short and ...

Abstract

The invention provides a large-current fast transformation high-transient-response power supply which comprises a lighting module, a time sequence control module and a power supply management functional module that are connected mutually, wherein the lighting module is connected with a front direct current power supply and a driving board, the front direct current power supply is subjected to voltage reduction to form a direct current low-voltage power supply to be output to the driving board; the time sequence control module is connected with the driving board and controls the delay starting of the driving board; and the power supply management functional module is used for converting an analog signal into a digital signal, collecting data information, interacting the data information with the outside and carrying out overvoltage protection on the power supply. According to the power supply provided by the invention, large-current output, current rapid transformation and high transient response of the power supply can be realized, and the power supply efficiency of the power supply is increased.

Description

technical field [0001] The invention relates to a transient response power supply, in particular to a high-current fast-transformation high transient response power supply. Background technique [0002] At present, the power supply technology of power LED DLP light source adopts AC-DC industrial control power supply scheme to realize power supply. When the mains power enters the power supply, it first passes through the choke coil and capacitor filter to remove high-frequency clutter and interference signals, and then passes rectification and Filter to get high voltage direct current. Then, through the switching circuit, the direct current is converted into high-frequency pulsating direct current, and then sent to the high-frequency switching transformer for step-down. After filtering through a large inductance and super-large capacitor for energy storage, the output is a low-voltage direct-current voltage for the driver board to drive the light bulb. The step-down of the tr...
