Reduce the standby power consumption of a microwave oven

Although it is turned off, it still consumes 1 to 3 W when it is plugged into an ac socket. In this design the touch panel microwave oven consumes 3mW when it is turned off and yet plugged in. A more effective circuit design for a touch panel microwave oven is proposed to reduce the standby power consumption, which is also easy to apply to future products. This power consumption in the standby state is lower than that of others and not only simple to set up but also inexpensive. EXISTING SYSTEM A microwave oven is a kitchen appliance that heats food by dielectric heating, using microwave radiation to excite polarized molecules within the food. Recently most microwave ovens have touch panels. But, unfortunately the power is not completely cut off when the oven is not used. The oven, which contains a clock, memory and a microcontroller, consumes electric power whenever it is plugged in, even though the oven is turned off. Most microwave ovens are plugged in 24 hours a day, 7 days a week. While such standby power often does not seem to amount to much, it really adds up. In some cases, a touch panel microwave oven consumes on the average more power for standby each year than for cooking. Many electric appliances have standby power consumption amounting to around 10%of a household’s total power. Therefore much research has been done into reducing standby power consumption in appliances and equipment by way of home energy management systems which both monitor and control the devices and are based on complex architecture.
  2. 2. PROPOSED SYSTEM In the proposed system, reduce the standby power consumption of a microwave oven. By using the current sensor, the current which is passing through wire and if it is not necessary and it will be automatically switch off through the switching. By using this proposed system power consumption will be advantages. By our proposed system, the human effect also been reduced. BLOCK DIAGRAM HARDWARE REQURIMENT 1. ARM-Controller 2.
