Description: 本文将总结我们公司所设计的各种电源电路，从中提炼出我们公司的电源平台，供大家参考。
我们通常用到的工作电压为12V和5V。12V主要用来驱动继电器工作或蜂鸣器，在本平台中将用＋12表示；5V将用＋5表示。在应用中，也用到24V和3V电源，分别用＋24和＋3表示。3V一般用在有电池做备用电源的场合。

Description: VIPower: 10W POWER SMPS USING VIPer22A
FOR AIR-CONDITIONER APPLICATION
1. ABSTRCT
New air-conditioner systems use two main lowvoltage
outputs to supply the internal electronic
equipment, respectively these values are +12V
and +5V. These low output voltages are generated
by a switch mode power supply. Many important
features are requested by the power supply: high
efficiency, light weight with compact size and low
power consumption in stand-by condition just to
mention some of them.
