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.

Summary

Introduction

Brushless DC Motor (BLDC) has been the powerhouse behind the rapid progress in electric powered vehicle, due to its high power to weight ratio and the level of efficiency that it could achieve. There are currently several gate driver integrated circuit with hardware programmable dead-time-insertion, some examples are the International Rectifier IRS25091SPbF and IXYS IX21844 which has a feature of build in programmable Dead-time insertion up to 5μS through selection of resistor As those hardware requires a manufacturing of a specific board to host it and physical resistor replacement to change the desired dead-time period, for low volume and interconnection to popular general processor board the associated effort and cost is not preferable. Nuratch, 2017) had demonstrated that a cheaper 16-Bit micro controller is capable to be programmatically functioning as a dead time insertion module for Half bridge DC-to-DC converter operation With this capability, it is believed that the uses of 16-Bit low cost micro controller will expand the selection of popular general processor to be used as motor controller. The proposed Dead-time insertion module will be designed to able to accommodate both sinusoid drive and its SPWM switching modulation as well as the trapezoidal drive PWM modulation with seamless transitional operation for both modes, while observing a Fault signal from IPM IGBT module as a part of dead-time effect mitigation strategy
