摘要： A multi-pulse transformer with multiple taps provides a constant magnitude voltage output to a variable speed chiller's compressor motor over a range of input voltages. The 3-phase transformer includes primary windings and a plurality of secondary windings. The secondary windings are electromagnetically coupled with the associated primary winding. The primary windings include taps for receiving multiple input AC voltages and the secondary windings have a single output terminal for supplying a predetermined output voltage which, after rectification produces a DC multi-pulse waveform for powering a DC link of a variable speed drive. Alternatively the 3-phase transformer includes multiple taps on the secondary windings. Each of the primary windings has a terminal for receiving an input AC voltage. The taps of the secondary windings provide an output voltage that is converted to a multi-pulse waveform for powering a DC link of a variable speed drive.

摘要： A ripple current that flows into a main-circuit capacitor is estimated based on a system impedance and output power to a motor, thereby making it possible to always perform ripple-current estimation and life estimation computation for the main-circuit capacitor online. Because data of the system impedance which largely affects the ripple-current estimation for the main-circuit capacitor is used, the capacitor ripple current can be estimated according to the magnitude of the system impedance. This enables highly-accurate life estimation computation of the main-circuit capacitor.
