Circuits using resistors and inducing they built in machines and equipment, small or large. They are also used for studies and analysis of dynamic systems of different areas, such as electrical, electronic, thermal, mechanical and fluidic. Due to the difficulty of finding the diversified trade numbers of inductances, and some non-ideal ones, such as internal resistance, coupled with the fact that components with inductance values for applications at low frequencies are expensive, bulky and heavy, this work is an emulation of an RL circuit synthesizing an inductance through circuits using resistors, capacitors and operational amplifiers. Data already in the literature and a proposed circuit were considered. Concordance between the emulator circuits and the RL circuit, both on time and in practice, is limited to how frequencies are often frequent, which tend not to use the frequency option for high frequencies. In spite of a circuit response, the response was improved considering a direct response to the permanent stress and the transient response to a degree, besides allowing a direct reading of the emulated voltages without resistor without inductor simultaneously. The results obtained allow to study the circuit and, with several new steps, arrive at a circuit that is suitable for an ideal RL circuit, with closer results when compared to the actual inductor. |
