Problems solved by technology

[0003] At present, most plasma display power supplies generally adopt forward and flyback output schemes when the display screen is small. The structure is simple and the performance is reliable, but the output power is limited, which cannot meet the power supply requirements of plasma displays with larger screens.

Embodiment Construction

[0015] Such as figure 2 As shown, the power supply part includes the commonly used main output control chip of the power supply, which is interconnected with the main output circuit of the power supply, and also includes the power standby circuit. The power standby circuit is not connected with the main output control chip of the power supply, and it is only connected with the power management chip and the interface Standby circuit connection. In standby mode, the control relay K is disconnected, the main output control part of the power supply, including the PWM Controller, is in a non-powered state, and does not work, and the main output part, including the transformer T1 and the three-terminal regulator 7815, do not work, so that the There is no fundamental electrical connection in the standby part of the power supply, and the power consumption of any standby circuit will not be consumed when the main circuit of the power supply is not working. When the main output is req...

Abstract

The disclosed method to reduce resonance-type plasma display power standby consumption comprises: adding an auxiliary output coiling to original output loop to lead input voltage after adjusted by PFC power factor and generate working power for a PWM controller through a T-shape stabilizer; thereby, on standby state, reducing power to zero; when need to provide power, attracting the relay, conducting circuit, using the SCR to provide soft-startup voltage for PWM control chip, and providing the voltage VCC from an auxiliary coiling to the control chip, and turning off the SCR. This invention has better energy-saving effect.

Description

technical field [0001] The method belongs to the technical field of gas discharge and relates to a plasma display power supply, in particular to a method for reducing the standby power consumption of a resonant plasma display power supply, which can reduce the standby power consumption of the plasma display. Background technique [0002] Plasma display is a display device that uses ultraviolet light generated by gas discharge in the display unit to excite phosphor powder coated in the display unit to emit light to display information. [0003] At present, most plasma display power supplies generally adopt forward and flyback output schemes when the display screen is small. The structure is simple and the performance is reliable, but the output power is limited, which cannot meet the power supply requirements of plasma displays with larger screens. For a few resonant topology structures adopted to meet the power supply requirements of large-screen plas...
