AC RMS to DC conversion circuit

The AC-to-DC circuit is a circuit that converts sinusoidal alternating current into direct current . If the input signal is not a sine wave , but a triangle wave or a sine wave
with relatively large distortion , the relationship between the average value and the effective value is 1.11 times, so the measurement The error will be relatively large. In this case, the average value is not used, but it is directly converted to obtain the AC effective value and then converted into DC. The circle shows the AC effective value and DC conversion circuit , which is mainly used for signal measurement. in the device.
