Introduction: DC Boost Converter
My first intention was to design a DC Voltage boost converter to convert 3vdc to 5vdc so that I could power my iPod or any other device requiring 5 volts to charge. I read about oscillation circuits and boost converter circuits and combined the two. My results were staggering when I was able to convert 4.5 volts to over 100 volts by accident. I decided to post an instructable for this instead, for now. If you have any tips to increase the efficiency or output current please comment below, I appreciate any suggestions.
Step 1: Obtain Parts
All components can be found at RadioShack.
3 X 1.5 volt Battery Holder
L1 RF Choke 100 micro Henries
R1 Resistor 10 Ohms
R2 Resistor 51K Ohms
Q1 PNP Transistor 2N3906
Q2 NPN Transistor 2N3904
Q3 Power MOSFET IRF510
C1 Capacitor .01 micro Farads
C2 Capacitor .047micro Farads
D1 Diode 1N4148
Step 2: Place Components
Arrange components as you see here or as close as possible.
Step 3: Observe Diagram
Look through the wiring diagram to see what components need to be connected to what prior to soldering.
Step 4: Solder Components
Solder components carefully to ensure there are no shorts, also ensure all connections are made at all points.
Step 5: Clean Up and Test
Trim component leads and clean solder joints. Be sure to double check connections to make sure a connection isn't left out. Hook up battery terminals and multimeter and see what you've got!!!
We have a be nice policy.
Please be positive and constructive.
