Below with a specific embodiment explanation present invention, say using single set winding generating terminal voltage as example
Bright.Such as nominal charging voltage value 29.6VDC of energy storage component, charging manager itself has at 3 times of wide pressures
Reason scope, i.e. m=3, then the output voltage of corresponding single set winding generating end all has at 21VAC-63VAC
Effect voltage, can charge through charging manager treatment and supplied energy storage component.Voltage such as simplex winding output
Being 10.5VAC, if without this circuit, then this voltage is dead voltage, after foregoing circuit is connected,
Voltage is upgraded to original 2 times and becomes 21VAC, effectively；Voltage such as simplex winding output is 12VAC, if

2 times become 24VAC, effectively；Voltage such as simplex winding output is 15VAC, if without this circuit,
Then this voltage is dead voltage, and after foregoing circuit is connected, voltage is upgraded to original 2 times and becomes 30VAC,
Effectively；Voltage such as simplex winding output is 20VAC, if without this circuit, then this voltage is invalid electricity
Pressure, after foregoing circuit is connected, voltage is upgraded to original 2 times and becomes 40VAC, effectively,
And the voltage of the 21VAC-63VAC sent for electromotor simplex winding is originally just in active voltage scope
In, it is not necessary to boosting, the most set winding parallels the most directly use the output voltage of simplex winding, as
When the voltage of simplex winding output is 22VAC, the most above-mentioned double winding parallel connection keeps magnitude of voltage constant,
In like manner, as simplex winding output voltage be 30VAC time, 40VAC time, during 50VAC, all allow during 60VAC
Above-mentioned double winding parallel connection keeps output to be exactly the set winding output of electromotor list to the magnitude of voltage of charging manager
