Abstract

In this paper the implementation of a simple yet high performance digital current mode controller that achieves high power factor operation for three phase Boost rectifier is explained. This objective is achieved without input voltage sensing and without transformation of the control variables into rotating reference frame. The controller uses resistor emulator concept for shaping of input current like input voltage in discrete domain. In implementation Texas Instruments's DSP based unit TMS320F240F EVM is used as the digital hardware platform. The algorithm is tested on a 4Kw ,670V DC Output, Boost rectifier. The execution time of the control algorithm is found to be less than $40\mu{sec}$.
