SYSTEM AND METHOD FOR CONTROLLING A VARIABLE SPEED DRIVE |
摘要 |
<p>A variable speed drive (104) is provided having a converter (202) to convert an AC voltage to a DC voltage, a DC link (204) to filter and store energy from the converter (202), and a plurality of inverters (206). Each inverter (206) is configured to convert a DC voltage to an AC voltage and is electrically connected in parallel to the DC link (204). An interleaved pulse width modulation control technique is used to control the operation of the plurality of inverters (206) and possibly the converter (202) to lower the RMS ripple current in the DC link (204).</p> |
