Power supply [1] provides power supply for relevant control and drive circuit；The by-passing signal that controller [2] exports, to bypass driver element [3], drives relay [4], and then control contactor [5] action or release；Bypass contact [6] is the normally-closed contact of catalyst [5]；The Regulation Control signal that controller [2] exports drives [7] to pressure regulation, drive one group of switching device in pressure regulation unit [9], control to connect the different taps of transformator [8], thus adjusting the output voltage of the low pressure winding of transformator [8], and then adjust the output voltage of power supply；Bypass instruction [10] is used to refer to the state of bypass.

Please referring further to Fig. 2, this is the Bypass Control of the lighting energy saving power supply for high-intensity gas discharge lamp.Controller [2] is MCT801D by control module M1(model) serve as；Pressure regulation drives [7] to be served as by M2 unit, it is provided that the triggering signal of bidirectional thyristor V1～V4；Bypass driver element [3] is made up of resistance R3, R4 and audion V5, one end of resistance R4 is connected with the PL pin controlling module M1, the other end is connected with the base stage of audion V5 and one end of resistance R3, and the other end of resistance R3 is connected with the emitter stage of audion V5, and ground connection；The coil of relay K J1 is in parallel with diode D1, and the anode of diode D1 is connected with the colelctor electrode of audion V5, and the negative electrode of diode D1 is connected to DC voltage VCC；Normally opened contact KJ1-1 mono-end of relay K J1 is connected to one end of catalyst, and the other end is connected to exchange common port N；Relay [4] is KJ1, and its contact is KJ1-1；Catalyst [5] is KM1, and bypass contact [6] is in parallel by two groups of normally-closed contacts of KM1-1, KM1-2；Transformator [8] is T1, has multiple pressure regulation tap；Pressure regulation unit [9] is made up of switching device bidirectional thyristor V1～V4；Lin is exchange input [11]；Lout is exchange output [12]；Exchange common port [13] is N；Bypass instruction [10] is made up of the auxiliary normally-closed contact KM1-4 of KM1, resistance R5, light emitting diode D2.

Transformator T1, has multiple pressure regulation tap, and its low pressure windings in series is between exchange input Lin and exchange output Lout.

Bypass contact [6] is normally-closed contact, in parallel by two groups of normally-closed contacts of KM1-1, KM1-2 of catalyst KM1, and is in parallel with pressure regulation unit [9] Zhong mono-road bidirectional thyristor element V4.Concrete method of attachment is: two groups of normally-closed contacts of KM1-1, KM1-2 of catalyst KM1 are in parallel, in parallel with varistor RV1 again, in parallel with the series arm of electric capacity C2 with resistance R2, the one end of the parallel connection unit formed is connected with the 7th lead-out wire of transformator T1 and the second plate of bidirectional thyristor V4, the other end is connected with exchanging common port N, and the first anode of bidirectional thyristor V4 is connected with exchanging common port N.The effect of varistor RV1 is that the peak voltage on normally-closed contact and bidirectional thyristor V4 is carried out amplitude limit, the effect of the series arm of resistance R2 and electric capacity C2 is to absorb the peak voltage on normally-closed contact and bidirectional thyristor V4, reduces dv/dt, di/dt value on bidirectional thyristor V4.

Operation principle is: be added to the armature winding of transformator T1 from the alternating voltage of Lin input, when controlling the PL pin output high level signal of module M1, by resistance R3, R4 provides bias voltage to audion V5 base stage, audion V5 saturation conduction, relay K J1 coil energized action, catalyst KM1 coil obtains voltage operation, bypass contact KM1-1, KM1-2 disconnects, the each tap of armature winding of transformator T1 is controlled by bidirectional thyristor V1～V4, by the bidirectional thyristor wherein turned on, corresponding for transformator tap is connected to exchange common port N, the voltage of transformer secondary output winding is equal to armature winding institute making alive divided by no-load voltage ratio, ac output voltage subtracts the voltage of transformer secondary output winding equal to AC-input voltage, the tap joint position that no-load voltage ratio is connected with IGCT is relevant, then, ac output voltage obtains adjustment, the power consumption of high-intensity gas discharge lamp is relevant to added voltage, the thus brightness of adjustable high-intensity gas discharge lamp and fractional energy savings.M2 is the triggering signal driving unit of bidirectional thyristor V1～V4, and it receives from the control signal controlling module M1, realizes electrical isolation by the optocoupler in M2, triggers corresponding IGCT then through the drive circuit in M2.

When controlling the PL pin output low level signal of module M1, audion V5 ends without bias voltage because of base stage, relay K J1 is failure to actuate, catalyst KM1 coil is in reset state because of no-voltage, bypass contact KM1-1, KM1-2 Guan Bi, whole numbers of turn of the armature winding of transformator T1 are received exchange common port, thus the output voltage of transformer secondary output winding is minimum, completes bypass functionality.Output voltage during bypass, slightly below line voltage, namely still has the energy-saving effect of low power saving rate under bypass condition, is suitable for the occasion that light fixture supply voltage is normal or voltage is higher and uses.During bypass, the normally-closed contact KM1-4 Guan Bi of catalyst KM1, power supply [1] the DC voltage VCC provided is added on light emitting diode D2 by contact KM1-4, resistance R5, and D2 is luminous, and instruction is in bypass condition.

Additionally, the normally opened contact KM1-3 of catalyst KM1 is for controlling module M1 offer bypass condition signal.

Owing to the present invention carries out Bypass Control at the high-voltage side of transformator, thus it is less to control electric current, and the capacity of required electrical equipment is little, with prior art switch bypass at major loop compared with, the volume of required bypass electrical equipment is little, cost is low, reliability is high.
