What is the role of a varistor?
Varistor is a resistor whose resistance value changes with voltage within a certain current and voltage range, or a resistor whose resistance value is sensitive to voltage. Abbreviated as VDR". The resistor body material of varistor is semiconductor, so it is a variety of semiconductor resistor. Nowadays, "zinc oxide" (ZnO) varistor is widely used. What is the use of varistor? The biggest feature of a varistor is that when the voltage applied to it is lower than its threshold "UN", the current flowing through it is extremely small, which is equivalent to a closed valve. When the voltage exceeds UN, it flows through Its current surges, which is equivalent to opening a valve. Using this function, it can suppress the abnormal overvoltage that often appears in the circuit and protect the circuit from overvoltage damage. Now our home color TV power circuit uses zinc oxide voltage Varistor, the threshold voltage of the varistor used here is about 270V. When the power supply voltage is less than 270V (the normal value is 220V), it is equivalent to non-conduction, and when the power supply is abnormal and exceeds 270V for a short time, it conducts Pass, limit the voltage to 270V.
