Fig. 2 is the circuit diagram two of one power supply control apparatus of the utility model.
Referring to FIG. 2, it is further spreading out on the basis of Fig. 1 embodiments, for feedback circuit 1：
The feedback circuit 1 includes voltage acquisition module 13, first resistor module 11 and second resistance module 12；Described
Two resistive modules 12 are serially connected between the first resistor module 11 and ground.
The voltage acquisition module 13 is the first resistor for obtaining basic voltage, and using the basic voltage
Module 11 is powered with the second resistance module 12.Voltage acquisition module 13, which may be used, can arbitrarily obtain voltage in field, and
Utilize the scheme that the voltage is resistive module power supply.Meanwhile basic voltage can be the voltage that can change, and unspecific voltage
Value.
The control circuit 2 is connected to the first segment between the first resistor module 11 and the second resistance module 12
Point, the voltage for acquiring first node can be the first feedback voltage, or the second feedback voltage.
The resistance value of the second resistance module 12 is adjustable, and the resistance value of the second resistance module 12 is adjusted to the first resistance value
When, the control circuit collects first feedback voltage from the first node；The resistance value of the second resistance module 12
When adjusting to the second resistance value, the control circuit 2 collects second feedback voltage from the first node.

Access can be formed between Q2,3rd resistor module 31 and ground, when second switch Q2 is opened, accumulator 4, the first winding
Can form access between L11, diode D1 and accumulator 4, so, by the switch change of second switch Q2, it can be achieved that
The different accesses of accumulator 4, by switching the power supply control, it can be achieved that accumulator 4 between two paths.
Specifically it can be understood as：The time that second switch Q2 is closed is longer, and the voltage exported through accumulator 4 is then bigger；
The time that second switch Q2 is closed is shorter, and the voltage exported through accumulator 4 is then smaller.

It is in ratio to be specifically as follows with the voltage at the first both ends winding L11.When diode D1 is connected, the first winding L11 both end voltages
It is identical as 4 both end voltage of accumulator.
In other alternative embodiments, it also can directly generate the basic voltage for meeting demand or self-supported side obtains basis
Voltage, as long as the first feedback voltage caused by capable of enabling triggers the different controls of energy storage for power supply circuit 3 from the second feedback voltage
System, and control result meets accumulator 4 to two kinds of power demands of load 5, does not just depart from the spirit of the utility model.
