| New regulation for Standby power consumption |
 |
 |
 |
|
There is a new regulation to the ECO conception directive (2005/32/EC) and applied for energy using products (or EuP) specifies that the maximum standby-mode or off-mode power consumption has to be between 1 or 2 W by 2010, and below 0.5 or 1 W by 2013. This new regulation will push appliance electronics designers to implement switched mode power supplies (SMPS). SMPS circuits are more often used to provide a positive output voltage. This paper explains that negative power supplies are preferred when AC switches such as snubberless Triacs, ACS and ACST devices are controlled by the electronics board. |
