Group unsteady flow branch route a phase phase winding M/N/P/Q, continued flow switch pipe V1/V4/V7/V10, field switch pipe V2/V5/V8/V11,
Power generation switch pipe V3/V6/V9/V12 composition, the one end phase winding M/N/P/Q is connect with continued flow switch pipe V1/V4/V7/V10 cathode
And positive terminal and 2 output cathode end of output negative pole end, that is, excitation main circuit, charging capacitor are inputted as phase winding unsteady flow main circuit 1
Device Cm negative pole end, battery X negative pole end, excitation main circuit 2 input negative pole end, and phase winding M/N/P/Q other end connection excitation is opened
Pipe V2/V5/V8/V11 anode, continued flow switch pipe V1/V4/V7/V10 anode, power generation switch pipe V3/V6/V9/V12 anode are closed, is encouraged
Magnetic switch pipe V2/V5/V8/V11 cathode inputs negative pole end, that is, 2 output negative pole of excitation main circuit as phase winding unsteady flow main circuit 1
End, power generation switch pipe V3/V6/V9/V12 cathode connect charging capacitor Cm as 1 output cathode end of phase winding unsteady flow main circuit
Positive terminal, battery X positive terminal and excitation main circuit 2 input positive terminal.
Excitation main circuit 2 is by input capacitor C1, transformer T, control switch pipe V13, diode D, output capacitor C2
Composition, input capacitor C1 anode input positive terminal as excitation main circuit 2 and connect the one end transformer T first winding a, transformer
The T first winding a other end connects control switch pipe V13 anode, and control switch pipe V13 cathode connects input capacitor C1 cathode simultaneously

Using operation of the duty ratio less than 1 under power generation switch pipe PWM mode in the work of winding unsteady flow branch, as long as passing through control switch
The PWM of pipe V13 adjusts the power generation output demand that can be completed, then the PWM control duty ratio of next power generation switch pipe is 1 (real
For simple venation wave mode).
Mode two, high excitation mode: control switch pipe V13 is greater than 0.5 using the duty cycle of switching of PWM chop control, encourages
Field switch pipe V2/V5/V8/V11 is closed when the magnetic stage starts, and the specific duty ratio size of control switch pipe V13 is according to detection
Charging current needed for obtained battery X charges and voltage are needed and are adjusted, after the excitation stage, field switch pipe V2/V5/
V8/V11 is disconnected and continued flow switch pipe V1/V4/V7/V10 is closed, into freewheeling period, due to the energization phase winding at this time
(being then the circuit M-V1-M assuming that being M phase winding) is not given to winding with voltage on current loop, electric current by rapid increase,
When reaching limit value before the maximum duration that phase winding electric current reaches freewheeling period setting, continued flow switch pipe V1/V4/ is disconnected
V7/V10 disconnects continued flow switch pipe V1/V4/V7/V10 when otherwise reaching the freewheeling period maximum duration of setting, then closure hair
Electric switch pipe V3/V6/V9/V12 enters power generating stage, and shutdown power generation is opened when reaching the power generation end time according to rotor-position signal
Pipe V3/V6/V9/V12 is closed, phase winding unsteady flow branch work terminates.
