6V to 12V Converter

Description: This inverter circuit can provide up to 800mA of 12V power from a 6V supply. For example, you could run 12V car accessories in a 6V car. The circuit is simple, about 75% efficient and quite useful. By changing just a few components, you can also modify it for different voltages. L1 is a custom inductor wound with about 80 turns of 0.5mm magnet wire around a toroidal core with a 40mm outside diameter. Different values of D3 can be used to get different output voltages from about 0.6V to around 30V. Note that at higher voltages...

This inverter circuit is designed to convert a 6V DC input into a 12V DC output, capable of supplying up to 800mA of current. This makes it particularly suitable for powering 12V automotive accessories in vehicles that operate on a lower voltage, such as certain British cars. The circuit's efficiency is approximately 75%, which is a reasonable figure for this type of inverter, indicating that some power is lost in the conversion process.

The core component of this inverter is the inductor, labeled L1, which is custom-wound with about 80 turns of 0.5mm magnet wire on a toroidal core with a 40mm outer diameter. The choice of a toroidal core is significant as it provides high magnetic efficiency and minimizes electromagnetic interference. The inductance value can be calculated based on the number of turns and the core material, which affects the overall performance of the inverter.

The circuit's output voltage can be adjusted by selecting different diode components for D3. The diode's characteristics, such as forward voltage drop and reverse recovery time, will influence the efficiency and the maximum output voltage range, which can be varied from approximately 0.6V to 30V depending on the diode used. This flexibility allows for customization of the inverter for various applications and load requirements.

The circuit may include additional components such as capacitors for filtering and stabilization, as well as resistors for current limiting or feedback control, depending on the specific design requirements. The simplicity of the circuit design allows for easy modifications, making it accessible for hobbyists and engineers alike who are looking to adapt the inverter for different voltage levels or load conditions.This inverter circuit can provide up to 800mA of 12V power from a 6V supply.
