Voltage Doubler with Diodes

Posted by on May 15, 2018 in Discrete-Circuits, Voltage-Multipliers

This is a Simple Voltage Doubler to boost 3V battery voltage to power some low-power 5V circuits. In needs a Clock input with high fan-out. You can use the 74HCT540 in parallel. Work with the Audio frequency range and see.

Mains Voltage Current LED Indicators

If you feed a Low Impedance Square wave, like output of 555, which has adequate Source-Sink Punch. to Input A, then it is quite possible you get double the voltage at B on No load.

Voltage Doublers and Multipliers

Posted by on Apr 14, 2016 in HV-Circuits, Voltage-Multipliers

Voltage multipliers are used to obtain low current high voltage, from an existing AC Source. Step up transformers can be used, but the insulation problems and care that has to be taken for HV above 1kV, make it difficult.

Mains Voltage and Power Circuits

After SMPS technologies and Ferrites were developed, HV for CRTs was generated by blocking oscillators and step up Transformers at High Frequency AC.
