    Abstract: A matrix converter includes a plurality of switching elements and is adapted to receive a multi-phase alternating current (AC) input signal having an input frequency and to generate a multi-phase AC output signal having an output frequency. The phases of the input signal are sorted as a function of their instantaneous voltage amplitude (60). A reference signal is generated from output reference voltages that correspond to each phase of the output signal (56). Duty cycles are calculated for each phase of the output signal based on the sorted input signal phases and the reference signal (62). Switching functions, which each control one of the switching elements, are then generated based on the duty cycles for each phase of the output signal (64, 66).

    Abstract: A powering arrangement (32, 34) for a device (30, 22) that normally operates on three phase power has the capability of operating based upon single phase power. One disclosed technique includes estimating a direct component based upon a measured voltage across the leads coupled with the single phase power supply. The quadrature component is estimated based upon a numerical derivative of the direct component. The direct component is also provided to a current regulator in a feed forward control manner, which minimizes error.

    Abstract: A three-phase regenerative drive (20) is operated based upon power from a single-phase AC source ( 12) and power from a DC source (14). The single-phase AC input power and the DC input power are converted to DC voltage on a DC bus (24) by a three-phase converter (22). DC power is provided from the DC bus (24) to a three-phase inverter having outputs connected to a motor (34). A controller (44) controls operation of the three-phase converter (22) based upon contribution factors of the AC and DC sources ( 12, 14) during motoring and regeneration. The controller (44) also controls an AC component of current from the DC source to reduce ripple current on the DC bus (24).

    Abstract: A system (10) continuously drives an elevator hoist motor (14) during normal and power failure operating conditions. A regenerative drive (30, 34, 36) delivers power to the hoist motor (14) from a main power supply (17) during the normal operating condition and from a backup power supply (24) during the power failure operating condition. A controller (12) operates the regenerative drive (30, 34, 36) to provide available power on the regenerative drive (30, 34, 36) to the backup power supply (24) during the normal operating condition.

    Abstract: Calibration of the state-of-charge (SOC) of a battery-based energy storage system used with a regenerative drive uses an SOC-open circuit voltage (V?oc#191) correlation. The battery is partially charged or discharged to assure operation defined by V?oc#191 following a known V?oc#191-SOC profile, such as a charge or discharge boundary curve. The partial charging/discharging may be synchronized with a traffic profile of an elevator system driven by the regenerative drive. A V?oc#191 measurement is made, and by enhancing the relaxation dynamics of V?oc#191 through regulating battery usage with a reference to traffic profile, a V?oc#191 is estimated more reliably. Using the estimate V?oc#191 and the known V?oc#191-SOC profile, state-of-charge of the battery is determined.

    Abstract: A system continuously drives an elevator hoist motor during normal and power failure conditions. A regenerative drive delivers power from a main power supply to the hoist motor during normal operation. A rescue operation circuit includes a backup power supply and is operable in the event of a failure of the main power supply to disconnect the regenerative drive from the main power supply and connect the back up power supply to the regenerative drive to provide substantially uninterrupted power to the hoist motor.
