Design Of Voltage Limiters

Design Of Voltage Limiters

Voltage limiters, also known as voltage suppressors, are devices that regulate the flow of electrical current in electronic circuits to prevent voltage spikes beyond a certain threshold. These voltage spikes may cause damage to sensitive electronic components, resulting in a costly repair or replacement. A good voltage limiter design should meet certain criteria to ensure its efficiency and effectiveness. Firstly, the limiter should have a fast response time to limit the duration of the overvoltage. This is achieved by using a low capacitance diode with a low breakdown voltage. Secondly, it should have a high surge current rating to withstand the high current surge produced by the overvoltage. Additionally, the limiter should have a low leakage current to ensure that it doesn't interfere with the normal operation of the circuit. Finally, it should be compact in size and easy to integrate into existing circuits. To enhance the efficiency of a voltage limiter, it is essential to test the device thoroughly with different levels of overvoltage to determine its capacity to suppress voltage surges. Additionally, voltage limiters should be installed as close as possible to the input port of the circuit and be of the size compatible with the circuit, to reduce the length of interconnects and hence minimize parasitic inductance.
