Transformerless Power Supply circuit

Transformerless Power Supply circuit

Transformerless Power Supply Circuit We will use a zener diode among other elements to acheive the Transformerless Power Supply circuit. This  means that our power supply will give a limited range current value (it will be a maximum and a minimum posible current that the power supply circuit can deliver). This power suply must be permanently connected to the circuit as a whole […]

Inverting Summing Amplifier using Op Amp

Inverting Summing Amplifier using Op Amp

Inverting Summing Amplifier using Op Amp

The inverting summing amplifier using op amp outputs a voltage equal to the sum of the voltages it has in its inputs. The following explanation is based on an adder of three inputs, but applies to an adder of any number of inputs

Full wave rectifier using center tapped transformer

Full wave rectifier using center tapped transformer

Full wave rectifier using center tapped transformer

This full wave rectifier requires a center tapped transformer. This additional end on the secondary winding of the transformer divides the voltage in this winding into two equal voltages. This additional end is grounded.
