transformerless

The simple configuration of a transformerless power supply circuit presented below is able to provide high current at any assigned fixed voltage level. The idea seems to have solved the problem of deriving high current from capacitive power supplies which earlier seemed a difficult proposition...

The proposed 12V, 5 amp smps battery charger circuit employs a flyback converter topology which results in the required smps based high current, compact, mains isolated converter design. Here, the a high power mosfet becomes the main switching component and is used for triggering the ferrite...

This transformerless power supply circuit is designed for medium current applications. During the negative half period, the capacitor C5 is charged to peak voltage network. Transformerless Power Supply Circuit Schematic The positive half wave will open the thyristor and the electric charge...
