Voltage Regulator with current limiter

Voltage Regulator with current limiter

There are times when the amount of current that is required of a power supply exceeds its potential.

If the current demand is very high, the pass transistor of the voltage regulator may be damaged. On these cases it is necessary that the circuit has an overcurrent protection.

Transistor - Zener diode Voltage regulator circuit

Transistor – Zener diode Voltage regulator circuit

Transistor – Zener diode Voltage regulator circuit

This circuit delivers an output voltage established by the voltage of the zener diode less 0.7 volts. The 0.7 volts is the average voltage drop between the base and the emitter of a transistor. (Vbe)

Basic Power Supply block Diagram

Basic Power Supply block Diagram

The Power Supply block Diagram Many electronic circuits need a direct current (DC) voltage source, but what we commonly find are voltage sources of alternating current (AC). In order to achieve a direct current voltage source, the alternating current input must follow a conversion process like the one shown in the chart below. The chart shows the operation of […]

Voltage. Electrical Potential difference

Voltage. Electrical Potential difference

What is Voltage? Voltage is the electrical potential difference caused by the accumulation of electric charges on a point, or a material. If we remove electrons from a material, its total electric charge will be positive. Remember that we are removing electrons, which are negatively charged, from a neutral atom (which has no charge). This causes the atom is no […]
