555 Voltage Doubler: 7 Steps instructables This Instructable uses a common 555 timer IC (available pretty much everywhere) to double the voltage of the input DC source while only using minimal external components. This circuit is only practical for low current devises where the input voltage (for the voltage doubler) is between 4 20Vs. Voltage Doubler Circuit using 555 Timer with Working Practical Voltage Doubler Project. Step up 6V DC to 10V DC using 555 timer is a practical voltage doubler project, which consists of different blocks such as power supply block for giving input supply voltage to the circuit, 555 timer that is connected in astable mode for developing a DC square wave, multiplier block, output voltage measurement block. 555 DC Voltage Doubler Circuit electroschematics The actual doubler circuit is made of D1, D2, C4 and C5 components. The 555 dc voltage doubler timer IC works as an astable multivibrator and generates a frequency of about 8.5 kHz. The quare wave output drives the final stage made of T1 and T2. This is how the doubler works: by a low amplitude of the signal, transistor T1 blocks while T2 conducts. Voltage Doubler Circuit Diagram and Explanation Voltage doubler is the circuit where we get the twice of the input voltage, like if we supply 5v voltage, we will get 10 volt at the output. Generally transformers are there to step up or step down the voltage, but sometimes transformers are not feasible because of their size and cost. So here is the easy voltage doubler circuit using 555 timer IC. Voltage Doubler Circuit schematic using 555, op amp & AC to DC Voltage doubler circuit using 555. Here circuit is a voltage doubler or DC to DC converter using a 555 IC. The circuit consists of an astable multivibrator circuit which generates a square wave at the output terminal 3, with a 50% duty cycle. Voltage doubler circuit using NE555 Electronic Circuits ... The circuit diagram of a very simple voltage doubler using NE555 timer is shown here. Here IC NE555 is wired as an astable mutivibrator operating at around 9KHz. The base of the two transistors (Q1 and Q2) is shorted and output of the astable multivibrator (pin 3) is connected to it. When the output ...
