When each SM on arm bridge is equipped with a voltage sensor, the simulation results are shown in Fig. 3.As seen in Fig. 3 (a), the capacitor voltage of the sub-module tends to be stable after 0.06 s, and the capacitor voltage of the sub-module fluctuates around 600 V, with a fluctuation amplitude of 43 V. The output current …
In their experiments, both Alom and Carol do without a two-way switch and instead simply disconnect the capacitor from the power supply to make it discharge through the resistor. As Alom mentions in the introduction, the uses of capacitors are quite interesting for giving the students some context here.
Since capacitance level sensors are electronic devices, phase modulation and the use of higher frequencies makes the sensor suitable for applications in which dielectric constants are similar. Working Principle: The principle of capacitive level measurement is based on change of capacitance.
