Why is the DC regulated power supply connected to the load circuit after the voltage is reduced
Resistor series with partial pressure parallel to the role of shunt
The power supply of the regulated power supply is insufficient or the internal resistance is large. At this time, the voltage will be reduced when the load is large. At this time the power supply performance will not be very good.
Heavy load, beyond the power load capacity.
The load of the power supply is too large, the load current is large, the internal resistance of the power supply is low.
1, the access load exceeds the actual power supply capacity of the power supply;
2, the power supply design problems: drive the drive force is insufficient, the base injection current is too small, the capacitor capacity is too small, etc.:
3, circuit parts have problems, resistance deterioration, transistor aging, etc.:
4, the AC power supply voltage is too low, AC low voltage side voltage is lower than the required voltage, etc.:
5, the transformer power is too low - inadequate.
