As power electronic technology evolves, the AC PWM inverter drive becomes more efficient, more compact, more advanced in performance, and less expensive. This tendency has been further accelerated in the small horsepower AC drives, particularly in the area of less than five horsepower range application. High Voltage Integrated Circuit (HVIC) technology has been one of the major contributing factor to achieve these objectives. The motor current sensing device is an important element in the AC motor drive, which provides IGBT protection information as well as linear current feedback information for control purposes.
Also, the paper contains info around effect sensor, analog circuit, output, gain error, current sensing, and performance data.
