How does a circuit change voltage?
Thread Content
How does a circuit change voltage? I now want to convert 12 volts to 6 volts. Resistor or diode?
What is the load on the circuit at the voltage level you need? That is, what current is required by your 6V load? For relatively low loads (below 500mA), a voltage regulator module 7806 can be added after the power supply. The dealer will tell you how to connect it when you purchase it.
Right now I only have primary components such as diodes and capacitors; I need to figure out how to add more
Use about 8 to 9 diodes (silicon diodes) connected in series to form a voltage-reducing silicon chain; be sure to match the size of the load to that of the diodes!
If the current is not high, a diode alone will suffice; the voltage drop across a diode when it is in forward conduction is 0.7V. By connecting 8 diodes in series between the positive terminal of the power supply and the positive terminal of the load, a voltage of around 6V can be obtained. Give it a try.
Thank you to the experts upstairs. I’d like to ask politely: are all diode-based voltage regulators the same?
Thank you, guys upstairs; I understand now that once a diode is in forward conduction, its forward voltage drop remains more or less constant (0.7V for silicon diodes and 0.3V for germanium diodes). By utilizing this property, it can be used as a limiting element in circuits to keep the signal amplitude within a certain range.
Silicon tube 0.7V； Germanium tube 0.3V.
