2. Description of the Related Art
From the point of view of environmental protection, restriction on standby power consumption of electrical appliances for energy-saving is being strongly imposed in Americas (EPA1.2) and Europe (ErP step 2) as well as in Korea. In order to cope with the restriction, various efforts are under way to reduce the standby power consumption of electrical appliances.
For example, an electromagnetic interference (EMI) filter for removing noise is included in an input of a power supply (e.g. a switch-mode power supply), and if electrical charges of an X-capacitor included in the EMI filter flow to a metal terminal of a plug during a plug-off state, a safety problem may occur. Accordingly, in order to solve the problem, a discharge resistor configured to discharge charges filled in the X-capacitor may be used. However, there is power consumption in a plug-on state due to the discharge resistor, which is against the effort for reducing the standby power consumption of electrical appliances. Therefore, measures to solve the problem are needed.
