principle
one
The working principle of the battery regulator is to use the voltage regulation of the circuit and the control of the circuit to control the current. Generally, when the voltage input changes, the regulator will be sampled and compared through the control circuit to drive the rotation of the servo motor, thus changing the position of the carbon brush of the regulator. By automatically adjusting the coil, the output voltage is more stable. So that electrical appliances can be used normally in the case of unstable voltage.
two
The first power regulators relied on the pulsation of relays to stabilize the voltage. When the grid voltage fluctuates, the automatic correction circuit of the power regulator starts to make the internal relay operate. Forcing the output voltage to remain near the set value, the advantage of this circuit is that the circuit is simple, the disadvantage is that the voltage regulation accuracy is not high and each relay jump shift will cause an instantaneous interruption of the power supply and generate spark interference.
3, the regulator is also an essential existence in life. Unstable voltage can cause fatal injury or misoperation of equipment, affect production, cause delivery delay, quality instability and other losses.
