とする交流エレベータ用制御回路の安全装置。 A converter converts alternating current into direct current, this direct current is smoothed by multiple smoothing capacitors connected in series, an inverter converts it into alternating current with variable voltage and variable frequency, and this converted alternating current causes induction. The converter has a circuit that drives the electric motor to operate the car and also cuts off its output when a cutoff signal is applied, and when the voltage applied to any of the smoothing capacitors exceeds the first predetermined value, The car is characterized by comprising a first circuit that stops the car at the nearest floor, and a second circuit that issues the cutoff signal when the applied voltage exceeds a second predetermined value that is higher than the first predetermined value. A safety device for control circuits for AC elevators.
