Abstract:

The conventional surge protection circuit requires a high-power level of circuit components, which leads to lower performance and higher hardware costs of the entire circuit structure. This paper presents the design of a low-cost anti-surge circuit with absorbing capacitance. Through theoretical analysis, software simulation, and experimental tests, it is proven that the designed circuit structure can increase the voltage grade and improve circuit stability by reducing the cost of the surge protection circuit with a lower power-level metal-oxide-semiconductor field-effect transistor (MOSFET).

Key words: surge, energy absorption, active module, buffer circuit, capacitor
