Power generation control 2 comprises microcomputer 5, bleeder circuit 6 and three-phase mixed electrical bridge circuit 7.
Stator coil 1a, the 1b of permanent magnet generator 1,1c are connected in node Na, Nb, Nc.Three-phase mixed electrical bridge circuit 7 is made of three diode 7a and three thyristor 7b.Three diode 7a are connected between minus side power line L2 and node Na, Nb, the Nc, and three thyristor 7b are connected between positive side power line L1 and node Na, Nb, the Nc.Three-phase mixed electrical bridge circuit 7 will be transformed to direct current by the alternating current that permanent magnet generator 1 produces.Bleeder circuit 6 is respectively with the alternating voltage dividing potential drop of node Na, Nb, Nc, and voltage after partial is outputed to microcomputer 5.
CPU52 is based on the magnitude of voltage that is obtained by A/D converter 53, the rotating speed of detection of engine 10 and change thereof.In addition, CPU52 carries out output current control and treatment described later according to the control program that is stored in memory 54, by giving triggering signal TR via the gate pole of 51 couples of thyristor 7b of I/O port, carries out the phase angle control of thyristor 7b.By the timing of control triggering signal TR, control is from the electric current of three-phase mixed electrical bridge circuit 7 outputs.
Between positive side power line L1 and minus side power line L2, be connected with storage battery 3 and electrical load 4.From the electric current supply of three-phase mixed electrical bridge circuit 7 output to storage battery 3 and electrical load 4.Thus, storage battery 3 is recharged, and electrical load 4 consumes electric power.
(1-2) action of power generation control
Then, the action to the power generation control 2 of present embodiment describes.Fig. 3 is the oscillogram of voltage of a node of expression three-phase mixed electrical bridge circuit 7.Fig. 3 represents the voltage between node Na and the minus side power line L2.In addition, the phase place of the voltage between node Na, the Nb of three-phase mixed electrical bridge circuit 7, Nc and the minus side power line L2 differs 120 ° each other.
As shown in Figure 3, during moment t0～t3, on node Na, present the voltage of half-wave waveform.During before the half-wave waveform rises, also present the voltage of noise.Therefore, the rising that is judged to be the half-wave waveform when the moment that voltage is surpassed 0 might be judged the rising zero hour of half-wave waveform by accident during the zero hour.
Therefore, the moment t1 that the voltage of node Na is reached predetermined threshold value TH is judged to be the rising zero hour of half-wave waveform.At this, threshold value TH is set at the inaccessible minimum magnitude of voltage of noise voltage value.Thus, can prevent to judge by accident the rising zero hour of half-wave waveform.
The CPU52 of microcomputer 5 detect from the rising of a half-wave waveform constantly t1 to the rising of next half-wave waveform constantly time of t1 as cycle of alternating voltage.In addition, CPU52 calculates the rotating speed of the rotor of permanent magnet generator 1 based on the detected cycle.Because the rotor of permanent magnet generator 1 and the bent axle of engine 30 together rotate, so the rotating speed of engine 30 equates with the rotating speed of rotor.
Fig. 4 is mutually part the oscillogram of voltage and one electric current mutually part of the triggering signal TR that carries out phase angle when control of thyristor 7b, three-phase mixed electrical bridge circuit 7.Fig. 5 is mutually part the oscillogram of voltage and one electric current mutually part of the triggering signal TR that do not carry out phase angle when control of thyristor 7b, three-phase mixed electrical bridge circuit 7.
Fig. 4 and Fig. 5 represent to give a thyristor 7b triggering signal TR, three-phase mixed electrical bridge circuit 7 node Na and the voltage between the minus side power line L2 and flow to the electric current of a node Na of three-phase mixed electrical bridge circuit 7.
In addition, the phase phasic difference of the voltage between node Na, the Nb of three-phase mixed electrical bridge circuit 7, Nc and the minus side power line L2 is 120 °.In addition, flow to 120 ° of the phase phasic differences of electric current of node Na, Nb, the Nc of three-phase mixed electrical bridge circuit 7.
As shown in Figure 4, under the situation of the phase angle control of carrying out thyristor 7b, the CPU52 of microcomputer 5 detects the rising t1 zero hour of the half-wave waveform of alternating voltage.Thus, CPU52 is based on the rotating speed of target output current value described later and engine 30, and calculating will make the timing of triggering signal TR rising.Thereafter, CPU52 rises the pulse of triggering signal TR in the timing of being calculated.Thus, thyristor 7b conducting is to diode 7a and thyristor 7b circulating current.Thyristor 7b stops t3 disconnection constantly in the rising of half-wave waveform.
In this case, in order to calculate the timing that triggering signal TR is risen, need stipulated time TA.Therefore, CPU52 can not make triggering signal TR rise through before the moment t2 of stipulated time TA at the rising t1 zero hour from the half-wave waveform of reality.CPU52 rises by making any time of triggering signal TR moment t2 stops t3 constantly to the rising of half-wave waveform during, can control flow to the electric current of node Na.Thus, can supply with the electric current of arbitrary value from three-phase mixed electrical bridge circuit 7 to storage battery 3 and electrical load 4.
As shown in Figure 4, at triggering signal TR under the situation that moment t2 rises, from the electric current maximum of three-phase mixed electrical bridge circuit 7 outputs.Under the situation of the phase angle control of carrying out thyristor 7b, will be called the maximum output current value of phase angle control from the maximum of the electric current of three-phase mixed electrical bridge circuit 7 outputs.
On the other hand, as shown in Figure 5, under the situation of the phase angle control of not carrying out thyristor 7b, the CPU52 of microcomputer 5 maintains high level with triggering signal TR.In this case, thyristor 7b stops keeping conducting state during the t3 constantly to rising at the rising t0 zero hour from the half-wave waveform.Thus, during the half-wave waveform, to diode 7a and thyristor 7b circulating current.Thyristor 7b stops t3 disconnection constantly in the rising of half-wave waveform.
Under the situation of the phase angle control of not carrying out thyristor 7b, will be called the maximum output current value of power generation control 2 from the value of the electric current of three-phase mixed electrical bridge circuit 7 outputs.The maximum output current value of power generation control 2 is bigger than the maximum output current value of phase angle control.
Fig. 6 is the rotating speed of expression permanent magnet generator 1 and from the figure of the relation of the output current of three-phase mixed electrical bridge circuit 7.In Fig. 6, solid line A represents the variation of the maximum output current value of power generation control 2, and dotted line B represents the variation of the maximum output current value of phase angle control.
As shown in Figure 6, the output current from three-phase mixed electrical bridge circuit 7 increases along with the increase of the rotating speed of permanent magnet generator 1.In addition, the maximum output current value of phase angle control is littler than the maximum output current value of power generation control 2.Particularly, under the low situation of the rotating speed of permanent magnet generator 1, the maximum output current value of phase angle control significantly reduces.
In the present embodiment, be under the situation below the maximum output current value of phase angle control at the target output current value, according to the target output current value, carry out the phase angle control of thyristor 7b.On the other hand, the target output current value than the big situation of the maximum output current value of phase angle control under, do not carry out the phase angle control of thyristor 7b.Under the sort of situation, can obtain the maximum output current value of power generation control 2 from three-phase mixed electrical bridge circuit 7.
Fig. 7 is the flow chart of output current control and treatment of the power generation control 2 that carries out of CPU52 of expression microcomputer 5.
In the following description, the phase angle control that will carry out thyristor 7b is called opens phase angle control, the phase angle control of not carrying out thyristor 7b is called disconnect phase angle control.
At this, the target output current value prestores and is stored in memory 54.The target output current value is based on for example two-wheeled 100 state and change.In this case, a plurality of target output current values are corresponding to two-wheeled 100 setting state.Two-wheeled 100 state is that idling mode, acceleration mode, the deceleration regime of for example engine 30 reaches at the uniform velocity state.Two-wheeled 100 state is not limited to these states.Perhaps, the target output current value also can be based on the charged state of storage battery 3 and discharge condition and is changed.For example, be that the target output current value changes to higher value under 0 the situation at the dump energy of the situation of the not fully charged situation of storage battery 3, storage battery 3 deteriorations or storage battery 3.Target output current value under these situations is set at the current value of electrical load 4 necessity at least.Under the fully charged situation of storage battery 3, the target output current value changes to lower value.
At first, the CPU52 of microcomputer 5 obtains target output current value (step S1) from memory 54.
Then, the CPU52 of microcomputer 5 detects the rotating speed (step S2) of permanent magnet generator 1 based on the output voltage of bleeder circuit 6.In this case, as utilize as described in Fig. 3, CPU52 detects time from the rising t1 zero hour of a half-wave waveform to the rising t1 zero hour of next half-wave waveform as cycle of alternating voltage, based on the cycle of being detected, calculates the rotating speed of the rotor of permanent magnet generator 1.The rotating speed of permanent magnet generator 1 equals the rotating speed of engine 30.
And then CPU52 obtains the maximum output current value (step S3) of phase angle control based on the rotating speed of the permanent magnet generator 1 that is detected.The maximum output current value of the rotating speed of permanent magnet generator 1 and phase angle control prestores and is stored in memory 54.In this case, CPU52 reads maximum output current value corresponding to the rotating speed that is detected from memory 54.Perhaps, the calculating formula that CPU52 also can preset by the rotating speed substitution that will be detected obtains the maximum output current value that the phase angle is controlled.
Then, CPU52 judges that obtained target output current value is whether than the maximum output current value big (step S4) of phase angle control.
Be that CPU52 disconnects (step S5) with phase angle control under the situation below the maximum output current value of phase angle control at the target output current value.In this case, CPU52 equals the mode of target output current value with the value from the output current of three-phase mixed electrical bridge circuit 7 when detecting the rising t1 zero hour of half-wave waveform, calculate the timing that triggering signal TR is risen.Thereafter, CPU52 during half and half wave-wave shape in and in the timing of being calculated triggering signal TR is risen.
For example, the relation of the maximum output current value of the rotating speed of permanent magnet generator 1 and phase angle control prestores and is stored in memory 54.In this case, CPU52 reads the maximum output current value that the phase angle is controlled based on rotating speed from memory 54, and the ratio of based target output current value and maximum output current value calculates the timing that triggering signal TR is risen.Perhaps, also the calculating formula that can preset by rotating speed and the substitution of target output current value with permanent magnet generator 1 is calculated the timing that triggering signal TR is risen.
Thus, supply with the electric current of the value that equates with the target output current value to storage battery 3 and electrical load 4 from three-phase mixed electrical bridge circuit 7.
Be judged to be the target output current value than under the big situation of the maximum output current value of phase angle control in step S4, CPU52 disconnects (step S6) with phase angle control.In this case, CPU52 is maintained high level with triggering signal TR.Perhaps, CPU52 rises triggering signal TR at the rising t1 zero hour of half and half wave-wave shape.Thus, supply with the electric current of the maximum output current value that equals power generation control 2 to storage battery 3 and electrical load 4 from three-phase mixed electrical bridge circuit 7.
(1-3) effect of power generation control 2
According to the power generation control 2 of present embodiment, be under the situation below the maximum output current value of phase angle control at the target output current value, carry out the phase angle control of thyristor 7b.Thus, export the electric current of the value that equates with the target output current value from three-phase mixed electrical bridge circuit 7.Therefore, can supply with the electric current of the value that equates with the target output current value to storage battery 3 and electrical load 4.
Particularly, under the high situation of the rotating speed of engine 30, can obtain bigger output current from three-phase mixed electrical bridge circuit 7.In this case,, can reduce the fuel consume of engine 30 thus, and can reduce emission amount of carbon dioxide from the electric current of three-phase mixed electrical bridge circuit 7 by phase angle control to storage battery 3 and electrical load 4 supply appropriate values.
In addition, the target output current value than the big situation of the maximum output current value of phase angle control under, do not carry out the phase angle control of thyristor 7b.Thus, export the electric current of the value that equates with the maximum target output current value of power generation control 2 from three-phase mixed electrical bridge circuit 7.Therefore, supply with to storage battery 3 and electrical load 4 and equal or near the electric current of the value of target output current value.
Particularly, under the low situation of the rotating speed of engine 30, the maximum output current value of phase angle control significantly diminishes.In this case, equal the electric current of the maximum output current value of power generation control 2, therefore can supply with as much as possible electric current to storage battery 3 and electrical load 4 near the sufficient value of target output current value from three-phase mixed electrical bridge circuit 7 output.
