Basic principles of DC power supply

Alone, the difference between the level of water can not maintain a steady flow of water, and by means of continuous water pump from the low to be able to maintain a certain level of water to form a steady flow of water. Similarly, the electrostatic field generated by the charge alone can not maintain a steady current, and by means of a DC power supply, the non-electrostatic effect (referred to as "non-electrostatic force") can be used to make the positive charge from the lower potential Through the internal power back to the higher potential of the positive pole, in order to maintain the potential difference between the two electrodes, resulting in a steady current.

Function and composition of power circuit

Each electronic device has a power supply circuit that supplies energy. The power supply circuit has three kinds of rectifier power supply, inverter power supply and frequency converter. Most common household appliances use DC power supplies.
