Claims

[Scope of utility model registration request]

In an elevator drive device in which power from a DC bus based on regenerative energy from an elevator drive motor is regenerated to an AC power source by a power source inverter of a sine wave inverter type with a constant PWM modulation frequency, , an elevator driving device comprising a single tuned filter whose resonant frequency is tuned to the PWM modulation frequency and reduces and eliminates the tuned frequency component.
