TransformerLess Power Supply 12V 100mA ElectroSchematics This is a transformerless power supply for low current applications. C1 is the X rated AC capacitor that reduces high volt AC. D1 D4 rectifies AC to DC and C2 removes ripples. R1 is the bleeder to remove stored current in AC when power is off. R2 limits inrush current. A Zener can be used in the output to get regulated DC. Caution! Transformerless Capacitor Power Supply Design Transformerless Capacitor Power Supply 12V 40mA The 200mA fuse will protect the circuit from mains during shot circuit or component failures. The 275V MOV (Metal Oxide Varistor) will protect from power supply spikes or surges. The X Rated Capacitor C1 is the core part of this power supply as it will drop the excess mains voltage across it. High Current Transformerless Power Supply Circuit ... The circuit of a high current transformerless power supply explained here hopefully, effectively handles the surge developing from power transients such that the output becomes free from the dangers, and provides the required current supply at the rated voltage levels. TransformerLess Power Supply electroSome Resistive TransformerLess Power Supply. Resistive Transformer Less Power Supply is similar to Capacitor Power Supply except that instead of Reactance it uses resistance to limit current. Thus here excess energy is dissipated as heat across the Voltage Dropping Resistor. Circuit Diagram Simple transformerless power supply circuit | ElecCircuit But I look around my home in a small appliance in China. They use the transformerless power supply circuit. They use a capacitor instead of a transformer. Thus, power supplies are smaller and lighter. Today, I collect these transformerless power supply circuit. So you can select as you want. Hopefully, it will be useful to you. How to Build a Low Cost and Efficient Transformerless ... Here we begin by discussing the drawbacks of capacitive power supply circuits and learn how they may be upgraded to form the ultimate “transformerless” power supply, which may be as effective as its other counterparts, yet will be very cheap to build (hardly 30 cents), as well as compact and lightweight. Moreover, it’s permanent. Transformer Less 12V Power Supply Out of LED Bulb Transformer Less 12V Power Supply Out of LED Bulb: Its actually a hack and a concept of reuse of scrap.
