The single-phase universal thyristor trigger board is a phase-shifting power controller that adjusts the voltage, current and power of electrical equipment by adjusting the thyristor’s on-angle
Performance and reliability of military grade thyristor trigger ASIC. The output trigger pulse has very high symmetry and stability, does not change with the ambient temperature, and does not need to change the pulse symmetry and stability in use
The limit is adjusted. Field debugging generally does not require an oscilloscope to complete. It can be widely used in various fields of industrial voltage and current regulation, suitable for resistive load, inductive load, voltage – secondary
Side and various rectification devices, etc
Mainly applied to the following loads:
★ Temperature control with nickel chromium, iron chromium aluminum, far infrared heating elements and silicon molybdenum rod, silicon carbon rod as heating elements. ★ Salt bath furnace, power frequency induction furnace, quenching furnace, molten glass temperature heating control.
* Rectifier transformer, power regulator (pure inductor coil), one – secondary side of electric furnace transformer, DC motor control.
★ Single phase welding machine, resistance welding machine, spot welding machine control and other tuning occasions.
* Single-phase fan pump speed control and energy-saving control
★ Voltage, current, power, light and other stepless smooth adjustment. The thyristor trigger circuit composed of a single junction transistor is shown in Figure 1, and the related voltage waveform of the trigger circuit is shown in Figure 2. With a single crystal
Compared with the relaxation oscillation circuit, the oscillation part of the circuit is the same, and the synchronization is realized by improving the power supply circuit. The sinusoidal alternating current of the autonomous circuit is reduced by the synchronous transformer T to a lower voltage
The low AC voltage is then changed to pulsed DC by a diode rectifier bridge. The role of the regulator VW and the resistor RW is “clipping”, and when the pulsating voltage is less than the regulator’s voltage value, VW does not conduct, two
The voltage at the end is equal to the output voltage of the rectifier; If the pulsating voltage is greater than the stable voltage value of the regulator tube, the VW will be pierced, and the voltage at both ends of the rectifier bridge will maintain the stable voltage value, and the part of the output voltage of the rectifier bridge that is higher than the stable voltage value will fall in
Resistor on RW. In this way, the voltage waveform at both ends of VW is similar to a trapezoidal wave, and this voltage replaces the DC power supply in the tension oscillation circuit to play a synchronous role.
Since the power supply of the oscillating circuit is trapezoidal wave, at the end and beginning of each half wave of the main circuit sine wave, the power supply voltage of the oscillating circuit is very small, the circuit does not oscillate, and the capacitor voltage is released to 0.
When the power supply voltage is close to the top of the trapezoidal wave, the oscillating circuit begins to work, and when the capacitor is charged so that the voltage at both ends reaches the peak point voltage Vp of the single-junction transistor, the single-junction transistor conducts the capacitance discharge and discharges electricity
The current flows through R1. And the parallel circuit of the “] pole of the touched thyristor forms an output, providing a trigger pulse for the thyristor to make the thyristor open. The circuit then enters the next oscillation period, but the thyristor passes through the conduction gate
The pole is out of control, a power supply voltage in half the oscillation circuit output pulse is only the first to play a trigger role, the following pulse is invalid. Near the end of the half cycle of the main circuit voltage, hold
The power supply voltage of the swing circuit enters the hypotenuse of the ladder wave and drops rapidly, the oscillating circuit stops vibrating, and the capacitor voltage is released to 0. So in every wave and a half of the main circuit, the capacitor always starts charging from
