Abstract

Motor control application, especially for medium to high power implementation, will benefit the most with the compactness and robustness of an Integrated Power Module of Insulated Gate Bipolar Transistor also known as IGBT IPM. Nevertheless, implementation motor control with a general purpose micro-processor without any advance timer functionality with IGBT IPM will be challenged by the Dead-Time switching requirement in its power switching implementation.

Further, a combined sinusoidal and trapezoidal drive of a motor control is also believed will provides a better control performance in term of lower torque ripple and higher motor top speed. This paper proposed a low-cost alternative to address the requirement by implementing a software based dead time functionality using the low cost 16-bit micro controller board with capability of serving up sinusoidal drive as well as trapezoidal drive for motor control application.
