止型周波数継電器。In a static frequency relay that receives a frequency signal from an AC power supply voltage of a static forward converter, a first pair of diodes extracts a positive polarity voltage of one phase-to-phase voltage of the AC power supply to a first smoothing capacitor side. and a transformer which inputs the positive polarity voltage of the phase-to-phase voltage whose drop has been absorbed by the first smoothing capacitor through a diode to one primary input;
A second pair of diodes that take out the negative polarity voltage of the phase voltage to the second smoothing capacitor side, and a negative polarity voltage of the phase voltage whose drop has been absorbed by the second smoothing capacitor are passed through the diode to the other side of the transformer. A static frequency relay, comprising: a circuit for a primary input of the transformer, and a frequency signal synchronized with the cycle of an AC power source is obtained from the secondary output of the transformer.
