Tranformerless power supply for low voltage application / Fazlina Hanim Nordin

In most non-battery applications, the power supply to the electronic circuits can be built using a step-down transformer connected to the ac supply line to step the ac voltage to desired amplitude, then rectifying that ac voltage, filtering with a capacitor or RC filter, and finally regulating the d...
