Claims (1)

[Scope of Claim for Utility Model Registration] (1) A rectifier and smoothing circuit simulator that calculates apparent power from the effective value voltage and effective value current supplied to the rectifying and smoothing circuit from an AC power source, which corresponds to the effective value voltage. DC voltage generation means for supplying a scalar voltage; and AC current generation means for supplying a vector current corresponding to the effective value current; A rectifying and smoothing circuit simulator characterized in that the apparent power is obtained by multiplying the apparent power by a current. (2) The alternating current generating means includes: an alternating current voltage source A that generates a trigonometric function signal corresponding to the frequency of the alternating current power supply; a multiplier U1 that multiplies the output signal of the direct current voltage source and the alternating current voltage source; a voltage dependent voltage source B that inputs the output voltage of the multiplier and supplies a voltage corresponding to the output voltage to the rectifying and smoothing circuit; 2. The rectifying and smoothing circuit simulator according to claim 1, wherein said apparent power is determined by multiplying said apparent power by a current supplied by said circuit.
