Description: The way that this circuit works is as follows. The AC line voltage is rectified by D1 and D2 which connects to a voltage doubler circuit made up of the two 22uf capacitors. The Flash Freq. Pot and the 10uf capacitor charge up which triggers the Diac and causes the triac to turn on. This allows the trigger transformer T1 to send a very High Voltage to the flash tube and lighting it. The flash timing is adjusted by the flash freq. pot.
The described circuit is a high-voltage flash circuit commonly used in photography and other applications requiring a brief burst of light. The main components include diodes, capacitors, a DIAC, a TRIAC, a transformer, and a flash tube.
The operation begins with the AC line voltage being fed into the circuit. Diodes D1 and D2 function as a full-wave rectifier, converting the AC voltage into a pulsating DC voltage. This rectified voltage is then utilized in a voltage doubler configuration, which is realized using two capacitors rated at 22 µF. The voltage doubler effectively increases the peak voltage available to the circuit, which is crucial for the subsequent high-voltage flash operation.
The flash frequency potentiometer (Flash Freq. Pot) and a 10 µF capacitor are employed to control the timing of the flash. As the circuit charges, the voltage across the capacitor gradually increases. Once the voltage reaches a certain threshold, it triggers the DIAC. The DIAC is a device that remains off until a specific breakdown voltage is reached, at which point it turns on sharply. This characteristic allows for precise timing control in the circuit.
Once the DIAC is triggered, it activates the TRIAC, which is a semiconductor device that can control high power. The TRIAC allows current to flow through the trigger transformer (T1), which steps up the voltage significantly. The high voltage output from the transformer is then directed to the flash tube, causing it to emit a bright flash of light.
The flash timing can be adjusted by varying the resistance of the Flash Freq. Pot, which changes the charging rate of the 10 µF capacitor. This adjustability is essential for applications that require different flash durations or intensities.
Overall, this circuit effectively combines rectification, voltage doubling, and high-voltage triggering to produce a reliable and adjustable flash output suitable for various lighting applications.The way that this circuit works is as follows.
