Title: Effective value measuring circuit for sine wave intermittent current
Inventor: MARUO TETSUHIRO
IPC: G01R19/02
Filed: 1986-10-21
Abstract: PURPOSE:To accurately measure the effective value of a sine wave intermittent current by finding the effective value of the intermittent current from the output voltage signals of a frequency counter and a holding circuit. CONSTITUTION:A comparator 11 detects the zero phase of the sine wave intermittent current after cycle control and converts it into a rectangular wave signal which is held at H level for the half-cycle corresponding time of a fed current. The frequency counter 14 inputs the rectangular wave signal and converts it into a voltage signal proportional to the frequency of the intermittent current. Then a peak value detecting circuit 12 receives the rectangular wave signal as a gate signal and outputs a voltage signal proportional to the peak value of the intermittent current and a holding circuit 13 holds this output voltage signal for a time corresponding to the repetitive period of the intermittent current. Then, an arithmetic circuit 15 is provided which calculates the effective value of the intermittent current from the output signals of the counter 14 and circuit 13 and outputs the effective value, and the peak value and frequency of the intermittent current are detected to find the effective value of the intermittent current. Further, the circuit 13 outputs the effective value output signal continuously even in the stop period of the intermittent current, so the accurate effective value can be measured without reference to the load rate of the intermittent current.
