The diagram illustrates an AC voltage regulator circuit built using bidirectional thyristors. Unlike circuits utilizing unidirectional thyristors, this design is both straightforward and dependable. As the grid voltage falls below 220V, the control voltage at the gate of the triac SCR2 diminishes proportionally, leading to a reduced conduction angle for VD2. This results in an increased voltage at the C1 terminal, which boosts the control voltage for the triac SCR1, thus raising the output voltage. Conversely, when the grid voltage rises, the output voltage decreases, achieving effective regulation.
In practical applications, these circuits are widely used in household appliances such as air conditioners, heaters, and ovens where precise voltage control is essential. The bidirectional nature of the thyristors allows for symmetrical voltage regulation across both positive and negative cycles, making it particularly suitable for alternating current systems. Additionally, the simplicity of the circuit reduces the risk of failure, ensuring consistent performance over time.
For engineers designing similar circuits, it's crucial to consider the load characteristics and ensure proper heat dissipation for the thyristors to prevent overheating. Furthermore, selecting components with appropriate ratings for voltage and current is vital to maintain system reliability. Overall, this design exemplifies how combining basic electronic components can yield robust solutions for complex problems.
