Description
技术领域Technical field
本发明涉及电视机技术领域,尤其涉及一种零功耗待机电路及零功耗待机电视。The present invention relates to the field of television technology, and in particular, to a zero power standby circuit and a zero power standby television.
背景技术Background technique
目前,中国是全球最大的家用电器生产和消费国之一。家用电器拥有量的迅速增长带来了巨大的能源消耗,同时也加重了对环境的污染。世界各国通过制定和实施能效标准、推广能效标识制度来提高用能产品的能源效率,促进节能技术发展,以减少有害物的排放和保护环境。At present, China is one of the world's largest producers and consumers of household appliances. The rapid growth of household appliances has brought huge energy consumption and increased environmental pollution. Countries around the world improve the energy efficiency of energy-using products by promoting energy efficiency standards and promoting energy efficiency labeling systems, and promote the development of energy-saving technologies to reduce harmful emissions and protect the environment.
在众多家用电器产品中,电视机的市场保有量一直处在前列。针对电视机的节能设计及节能算法已经大量的应用在现有的产品设计中。按照现有的国家能效标准,电视机的待机功耗需小于0.5W,即电视机在接通AC电源时,电视机处于待机状态时的整机功率必须小于0.5W。Among the many household appliances, the market share of TV sets has been at the forefront. The energy-saving design and energy-saving algorithms for TVs have been widely used in existing product designs. According to the existing national energy efficiency standards, the standby power consumption of the TV set needs to be less than 0.5W, that is, when the TV is turned on, the power of the whole machine when the TV is in the standby state must be less than 0.5W.
现有的电视机***中,待机原理是通过低功耗的电源管理MCU关掉AC电源,使得AC电源大功率输出处于非工作状态。但是由于MCU自身也是耗能设备,需要给该MCU进行供电,如使用一个低功耗待机电源或电池给该MCU供电,使得在待机过程中,电源管理MCU继续耗电,造成电能浪费。如何减少电视机在待机状态的功耗是目前亟需解决的问题。In the existing television system, the standby principle is to turn off the AC power through the low-power power management MCU, so that the AC power high-power output is in a non-working state. However, since the MCU itself is also an energy-consuming device, it is necessary to supply power to the MCU, such as using a low-power standby power supply or a battery to supply power to the MCU, so that during the standby process, the power management MCU continues to consume power, resulting in wasted power. How to reduce the power consumption of the TV in standby mode is an urgent problem to be solved.
