AI Technical Summary
When controlling the capacitance value of the adjustable capacitor, how to effectively proofread the current capacitance value of the adjustable capacitor to avoid capacitance damage if the capacitance value does not reach the expected or exceeds the limit range.
By constructing a test circuit for the AC source, test resistor and reactance unit, the AC source outputs AC power at the preset angular frequency, the voltage ratio of the test circuit is obtained at intervals, and the monitoring capacitance value of the adjustable capacitor is determined based on the resistance value, the angular frequency, the fixed reactance value and the voltage ratio, and finally stop adjusting and determine the current capacitance value.
The current capacitance value of the adjustable capacitor is easily proofreaded, avoiding the capacitance value exceeding the limit range during the adjustment process, protecting the adjustable capacitor, and ensuring the accuracy and stability of the capacitance value.
