Abstract

The invention discloses a compensating circuit used for measuring alternating voltage and provided with a programmable capacitor array. The compensating circuit comprises a pair of first wires connected onto an alternate current circuit, an adjustable capacitor electrically connected onto the first wires and used for providing different capacitance values according to the programmable capacitor array, and a control unit electrically connected to the first wires and used for changing the capacitance value of the adjustable capacitor to the capacitance value of one capacitor in the programmable capacitor array according to an external order. As the capacitance value of the compensating circuit is changeable, an alternating voltage meter designed with the compensating circuit can measure the voltage in a wide frequency range.

Description

technical field [0001] The present invention relates to a compensation circuit. In particular it relates to a compensation circuit for AC voltage measurement with a programmable capacitor array. Background technique [0002] The AC voltmeter is a device that is very commonly used in everyday life. Traditionally, AC voltmeters use a resistor divider with a large impedance and including several capacitors. Naturally, the AC voltmeter becomes a low pass filter. For an AC power source with a frequency above 500 Hz, the measurement result is not accurate because of the attenuation of the signal strength. [0003] please see Figure 1A and Figure 1B . Figure 1A An AC voltmeter of conventional design is shown, the AC voltmeter includes two resistors R1 and R2 used as a resistor divider and a capacitor C1 to form a detection unit to obtain the AC voltage for use as Further measurements. Figure 1B Shows how the signal strength varies with the frequency of the AC power. Clea...
