Guest haresh prajapati Posted September 23, 2014 Report Posted September 23, 2014 Hello to all of youi am design a AC to DC charger for the usb devices. so in this when devices(load) is connected then and then charger is work otherwise not work. In short i am saving a energy is it possible????If it is possible then which circuit is used for the load detector??????? Quote
audioguru Posted September 23, 2014 Report Posted September 23, 2014 When a charger or power supply has no load then its power consumption is very low. If you detect that it has no load and disconnect it then the new detect/disconnect circuit might waste more power that you save. Quote
