Description

Charge type rectification regulator of permanent-magnet generator

The invention belongs to tractor electrical equipment.

Permanent magnetism generator volume is little, the efficient height, and the life-span is long, dependable performance, price is low, is widely used in middle-size and small-size engine.But, can't adopt the adjuster of existing excitation-type generator to regulate because it does not have excitation structure.The regulation technology of magneto-electric generator is still unresolved at present, its power output is severely limited, and the charge power of modern engine institute distributor increases day by day, causes magneto-electric generator danger on the verge of being replaced.

The present invention adopts homophase triggering technique (seeing patent application case No. 85107695) to finish a kind of charging of permanent magnet generator, the circuit design of rectification adjuster, the alternating current of permanent magnet generator output can be become direct current, charges for battery automatically.When reaching rated value, cell voltage automatically shuts down, and open-minded voluntarily when cell voltage is lower than rated value, thus solved magneto-electric generator regulation technology problem.

Implementation method of the present invention and operation principle are as follows:

As shown in the figure, the single phase alternating current (A.C.) electric wave that magneto-electric generator G is exported is transported to the single-phase half-controlled commutating circuit of being made up of SCR1, SCR2, D1, D2, and this loop has rectification concurrently and gives electricity, the dual-use function that pond charging and controlled phase shift are turn-offed.The major loop of rectification charging is a thyristor half control bridge, and its control triggers the loop and adopted the homophase trigger theory.D1, D2, D3, D4 form the single-phase bridge rectification loop in parallel with major loop, and it is triggered the loop for control power supply is provided, and is again trigger signal source.R1, DW, C form the sample of signal end, are connected on after R1, DW, the C series connection between the negative pole of the negative electrode of SCR1, SCR2 and D1, D2, and the base stage of BG1 is connected between DW and the C.The numerical value of sample of signal is determined by voltage-stabiliser tube DW.When cell voltage did not reach nominal value as yet, the internal resistance of DW was very big, the output of sample of signal this moment end no signal, and after cell voltage reached nominal value, the internal resistance of DW descended rapidly, a signal voltage that certain amplitude is arranged is just obtained in the loop.Change the value of R1, can change the output current of sampling loop.R2, R3 and BG1 form voltage control loop, and it is actually a direct current amplifier.Its operating state is: by, saturated, amplify.When sample of signal end no signal was exported, this amplifier was in cut-off state, sampled signal hour, amplifier is in magnifying state, and sampled signal is enough greatly the time, amplifier then is in saturation condition.The different choice of R2, R3 can change its operating state.Form phase shift by R4, BG2, R5 and trigger the loop, in fact it is an emitter follower, is transported to two SCR after the variable condition of BG1 can being amplified by electric current.When cell voltage was lower than nominal value, BG1 ended, and BG2 exports a sine wave signal.This signal is sent to the gate pole of SCR1 and SCR2, the thyristor conducting, and adjuster charges the battery; When cell voltage was in the nominal value critical value, thyristor was by phase shift, and output current descends, and cell voltage reaches after the nominal value, and thyristor is turned off, and charging stops.Add load, cell voltage descends, and thyristor is conducting voluntarily again, repeats above-mentioned charging and turn off process.

Performance of the present invention and purposes.This adjuster has self-commutation, charging and function such as controlled phase shift shutoff automatically; Voltage-regulation scope: 13.5-14.5 ± 0.1 volt; The rectification charging electric current is as the criterion with the rectifier output current; The environment for use temperature range can reach-55 ℃-100 ℃.

But the present invention's design mix is from component type or ic-type product.Also can be designed to built-in type or fitted outside product, also can be designed to the full-wave rectification form.Can be used as medium and small engine with the charging regulator of permanent magnet alternator; Can be used for various delivery formula single-phase generators as the rectification adjuster of using for all kinds battery charge; Also can be used as the single-phase charger in the various fixed electronic devices.Product of the present invention has the little lightweight advantage of volume.
