The figure below shows circuit of the simple voltage doubler and inverter.
I don’t know it is use full for you.
Working of Voltage Doubler
The circuit diagram for voltage Doubler is shown below. The circuit consists of three capacitors of 1μF and four control switches. Input voltage is connected across the capacitor C1. There are two steps of energy transfer. During the first step, Switches SA1 and SA2 are closed and SA3 and SA4 are open. Charge now transfers from C1 to C2 until their voltages become equal in value and polarity. During the second step, switches SA3 and SA4 are closed and SA1 and SA2 are open. Now the charge transfers from capacitor C2 to C3.till both attain the same charge.
When these two steps are repeated sufficient no: of times, the output capacitor C3 attains the charge of the input capacitor C1
Nodes A and D are connected to +5V power supply.
We have the equation
VA-VB = VC-VD
VA=VD=5V
VB = 0V
VC = VA+VD-VB
=10V
The output is taken from node C which is the double of the input voltage.
Working Voltage inverter:
The circuit diagram for voltage inverter is shown below. The circuit consists of three capacitors of 1μF and four control switches. Output voltage from the doubler is connected across the capacitor C4 The steps of energy transfer are same as that of doubler. During the first step, Switches SB1 and SB2 are closed and SB3 and SB4 are open Charge now transfers from C4 to C5 until their voltages become equal in value and polarity. During the second step, switches SB3 and SB4 are closed and SB1 and SB2 are open. Now the charge transfers from capacitor C5 to C6.till both attain the same charge.
When these two steps are repeated sufficient no: of times, the output capacitor C6 attains the charge of the input capacitor C7
Nodes F and G are connected to ground potential.
We have the equation
VE-VF = VG-VH
VF=VG=0V
VE=10V
VH= -VE=-10V
The output is taken from node H which is of opposite polarity of input voltage.
