Description
Technical field
The utility model relates to silicon controlled pulse phase shift triggering technique in a kind of permanent magnet generator voltage regulator.
Background technology
At present, the voltage regulator that connects with Thee-phase alternating current permanent-magnetic generator, all adopt " three-phase controllable silicon is positive semi-controlled bridge rectifier circuit altogether " to control the output dc voltage of permanent magnet generator, this technical scheme is illustrated in disclosed notification number CN2212850 patent on November 15 nineteen ninety-five " automobile AC permanent-magnetic generator voltage regulator ", its typical case represents circuit such as accompanying drawing 1, and product goes on the market already.Its operation principle is summarized as follows: when A-C point to point voltage is lower than the rated value of output voltage, because the barrier effect of voltage-stabiliser tube DW, triode T1, T2 ends, resistance R 3 couples of triode T3 provide base current, T3 enters saturation condition, the A point is by resistance R 4, T3 links to each other with the B point, by diode D1 or D2 or D3 controllable silicon Q1 or Q2 or Q3 is triggered as for the B point again, and very big randomness is arranged, has only certain minimum thyristor of the relative A point of negative electrode current potential, and when the current potential difference can form greater than thyristor trigger current value on R4 between negative electrode and A point, this controllable silicon triggered, and electricity generator stator coil is connected with output circuit; Otherwise, T1, T2 is saturated, and T3 ends, and three thyristors all turn-off, the circuit no-output.
This technical scheme exists deficiency, its shortcoming one: among Fig. 1, and three triode T1 in the controlling of sampling circuit, T2, T3 are operated in the on off state of " on-off " repeatedly, three controllable silicon Q1, Q2, the triggering and conducting probability of Q3 is at random, the triggering and conducting angle also is at random.In the thyristor turn-on cycle, high electromotive force on the electricity generator stator coil (about 80V when generator is unloaded at a high speed) is not added control ground with load circuit (GB is defined as 14.5V) directly be communicated with, the big electric current of the generator-adjuster of flowing through-load produces very big thermal losses in various internal resistances; When thyristor all turn-offed, load circuit was again less than supply of electrical energy, and equipment is in " leaving unused " state, and after tested, under the generator fast state, to storage battery load charging, the turn-off time is tens times of ON time approximately; " on-off " cycle of three thyristors is subjected to capacitor C 1, resistance R 1, and the charge-discharge circuit time constant influence that R2 formed is about 30ms, and also longer than the 10ms cycle after 50 hertz of civil power full-wave rectifications, the ripple of output voltage is serious.Inferior power supply quality causes the China that enriches rare earth resources, and the permanent magnet generator with energy-efficient title but can not obtain penetration and promotion.
Shortcoming two: Fig. 1 circuit, be not suitable for the load circuit of pure resistance, for example lighting bulb load, this class load request all should carry out controlling of sampling to the peak value and the effective value of output voltage, but the sample circuit of Fig. 1 take to as if average voltage, circuit can only be operated in " on-off " state, and what can regulate is the time scale of break-make, and can not regulate the peak value and the effective value of output voltage.When generator operation speed was high slightly, the high-tension high-power of output very easily burnt load.Such sampling conducting technical scheme, making permanent magnet generator be unworthy of charged bottle just can not be to the pure resistor load power supply of independent lighting bulb class, the advantage of " permanent magnet generator can generate electricity without storage battery ", so far be not put to commercialization, owing to weight or cost reason do not dispose portable vehicle, internal combustion engine and the agricultural machinery and implement of storage battery, can not use cheap permanent magnet generator.
Shortcoming three: among Fig. 1, triggering to thyristor is a direct current triggering technique scheme, nearly 10 times of the permanent magnet generator rotation speed change that connects with vehicle, the floating voltage peak value of electricity generator stator coil output changes about between 8-80V, among Fig. 1 the size of trigger current approximate electric current that the generator output voltage peak value produces on resistance R 4 when the R4 value bigger than normal, generator is under the low speed situation, because trigger current is little can not to trigger thyristor, circuit just can not externally be powered, and has influenced the low-voltage power supply characteristic of circuit; And the R4 value is less than normal, generator under high speed conditions, the power consumption of comparing electric current about 10 times under the low speed situation and 100 times that R4 is last to be produced, except energy consumption was too big, also the control utmost points to resistance R 4 itself and thyristor caused potential safety hazard.
