The quartz lanterns are mainly a transformer circuit developed on the basis of the high -frequency electronic ballast circuit. The electron transformer is the switching voltage voltage power supply, which is actually a inverter.Let me introduce it in detail below!
What is a quartz light electronic transformer
The quartz light electronic transformer is mainly a transformer circuit developed on the basis of the high -frequency electronic ballast circuit.The electronic transformer is the switching voltage voltage power supply.It is actually a inverter.It is mainly composed of protective circuits, bridge rectifier circuits, oscillation circuits, and isolation output circuits.It first transformed AC power to DC electricity. Then use electronic components to form a oscillator DC electricity to high -frequency AC electricity. The voltage required by the switch transformer output is used for secondary rectification electrical appliances.
Principle
The working principle of the quarterly lamp electronic transformer is similar to the switching power supply. The diode VD1 ～ VD4 constitutes the rectifier bridge to turn the citys electricity into a DC.Then, the high -frequency high -voltage pulse is lowered by the iron oxygen output transformer T2 to obtain the required voltage and power.R1 is a current -limiting resistor.Resistance R2, capacitor C1, and two -way trigger diode VD5 to make a start -trigger circuit.The triode VT1 and VT2 are S13005, and the B is 15-20 times.You can also use BUCEO> = 35OV high -power triode with C3093.Trigger the DB3 or VR60 with a diode VD5.The oscillating transformer can be made by self -made, and the audio cable is winding on the magnetic ring of the H7 X 10 X 6.Tia and T1B around 3 turns, TC 1 turning around.The iron oxygen output transformer T2 also needs to be self -made, and the magnetic heart uses an EI -type iron oxygen body with a edge length of 27mm, 20mm wide, and 10mm thick.The T2A uses a diameter of 0.45mm high -intensity lacquer cable to surround 100 turns, and the T2B has a diameter of 1.25mm high -intensity paint cable around 8 turns.The diode VD1 ～ VD4 uses IN4007, and the diode is triggered by the diode. The DB3 type is used.When the circuit works, the working voltage of point A is about 12V; point B is about 25V; point C is about 105V; point D is about 10V.If the voltage does not meet the above values, or the circuit does not oscillate, check the circuit whether there is any error welding, leakage or virtual welding.Then check whether the VT1 and VT2 are good, and whether the phase of the T1A and T1B is correct.After the entire circuit is successfully installed, it can be installed in a small box made of metal materials, which is good for shielding and heat dissipation, but it must be noted that the insulation of the circuit and the shell.In addition, changing the number of turns of T2 A and B two coils can change the output high -frequency voltage.
