How to Convert AC to DC: 6 Steps (with Pictures)1. Determine what your AC input voltage is. In North America and parts of Central and South America, the AC voltage at most sockets is 1. In Europe, Asia, Australia and most of the Middle East and Africa, it's 2. The standard in other areas may differ. Find the voltage and amperage needed to power the components of your electronic device. Check the manufacturer's instructions, if necessary. This DIY 12V to 220V DC to AC converter is built with CMOS 4047 that is the main component of this small voltage converter that transforms a 12VDC into 220. Edit Article How to Make an AC DC Converter. Questions and Answers. Alternating current (AC) is used for power line transmission and for high power devices like. Intro: mini cheap ac to dc converter. my friend told me to or simply challenged me to make a converter that is easy.i can not make difficult things but this one was. Intro: DC-to-DC Converter. I built this DC-to-DC converter for my 48V electric bike because I wanted to be able to plug-in some common 12V accessories. A solid-state AC-AC converter converts an AC waveform to another AC waveform, where the output voltage and frequency can be set arbitrarily. How to Convert DC to AC. outlining the logic of how to convert DC electricity into AC. ALTERNATOR AC to DC Power Supply Converter. Too much of either amperage or voltage will destroy the components, while too little will not allow the device to work correctly. Most have a safe range; aim for the center so your input power can vary somewhat. Use a transformer to step down the output from high- voltage AC to low- voltage AC. Electrical current enters the primary coil of the transformer and induces a current in the secondary coil, which has fewer coils, resulting in a lower voltage. Little power is lost in this process because the amperage increases in relation to the decrease in voltage. Run the low- voltage AC through a rectifier. A rectifier usually consists of 4 diodes arranged in a diamond shape - - a type called a bridge rectifier. A diode only allows current to pass in 1 direction; the diamond configuration allow 2 diodes to pass the positive half of the current and the other 2 diodes to pass the negative half. The output of both sets is a current that climbs from 0 volts to the maximum positive voltage. Add a large electrolytic capacitor to smooth out the voltage. A capacitor stores an electrical charge for a short time and then releases it slowly. The input from the rectifier resembles a string of humps; the output of the "smoothing capacitor" is a somewhat steady voltage with ripples. Pass the output of the smoother through a regulator. This smooths out the ripples and creates a very steady current that will operate your electronic device without damaging it. Regulators are integrated circuits and can either have fixed or variable output voltages. Although regulators include protection against excessive current and heat, yours may still require that you attach a heat sink to keep it from becoming too hot.
