The main component of a Transformerless power supply circuit is a Voltage dropping capacitor or X-rated capacitor, which are specially designed for AC mains. This X-rated capacitor is connected in a series of Phase lines of AC, to drop the voltage. \u003cbr\u003e\u003cbr\u003e This is a low-current \u003cstrong\u003etransformerless power supply\u003c\/strong\u003e for small applications. The capacitor reduces the high volt AC. D1-D4 rectifies AC to DC and second reduces ripples. The Zener diode is used to get regulated DC output. The Zener value can be changed to get other output voltages.\u003c\/p\u003e\n\u003cp\u003eThis \u003cstrong\u003epower supply\u003c\/strong\u003e is suitable when designing for an application that requires low power and where cost and size are of great consideration as the expensive and bulky transformer is eliminated in this type of power supply. All the components in this circuit are sized so that the circuit can deliver 12 volts and 30mA of current at the output to the load.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eBlock Diagram\u003c\/h3\u003e\n\u003cdiv id=\"p_info\" style=\"text-align: start;\"\u003e\u003cimg alt=\"Transformerless-Power-Supply-block-diagram\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/files\/Transformerless-Power-Supply.jpg?v=1633496311\" style=\"float: none;\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003ePhysical Attributes\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003eDimensions (cm) L x W x H : 20 x 15 x 5\u003c\/li\u003e\n\u003cli\u003eWeight (gm): 200\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eProduct Video\u003c\/h3\u003e\n\u003cdiv id=\"p_video\"\u003e\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/USxsrcrVoU8\" height=\"400\" width=\"800\" allowfullscreen=\"\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" frameborder=\"0\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003cdiv id=\"p_video\"\u003e\u003ciframe width=\"800\" height=\"400\" src=\"https:\/\/www.youtube.com\/embed\/6rmErwU5E-k\" title=\"YouTube video player\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen=\"\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003cdiv id=\"p_video\"\u003e\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/Fp37DPZVdRI\" height=\"400\" width=\"800\" allowfullscreen=\"\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" frameborder=\"0\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003c\/div\u003e","brand":"KitsGuru","offers":[{"title":"DO IT YOURSELF","offer_id":40708889968821,"sku":"LGKT113","price":399.0,"currency_code":"INR","in_stock":true},{"title":"READY TO USE","offer_id":40708890001589,"sku":"LGKT113_R","price":599.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/products\/Transformerless-Power-Supply-Circuit-DIY-Project.jpg?v=1633497051","url":"https:\/\/kitsguru.com\/fr\/products\/transformerless-power-supply","provider":"KitsGuru","version":"1.0","type":"link"}
