Document Type and Number:
WIPO Patent Application WO/2017/084291
Kind Code:
A1
Abstract:
Disclosed in the present invention are a high-power power supply for use in a display apparatus, and a display apparatus, the high-power power supply for use in a display apparatus comprising an alternating current conversion module used for rectifying an external alternating current power supply into a direct current power supply; a power factor correction circuit used for implementing power factor correction of the direct current power supply and for outputting a correction completion signal after successful correction;
a power-on control circuit used for powering on the power factor correction circuit after receiving a power-on signal, in order to implement power factor correction of the direct current power supply, and for powering on resonant control circuits after receiving the correction completion signal; resonant control circuits used for controlling the normal operation of a plurality of transformers; and a plurality of transformers for respectively providing a working voltage to the display apparatus. The technical solution of the present invention has the advantage of being low cost.
