  • Investigation and mitigation of the adverse effects of PWM adjustable speed drives

    Creator:
    Zhang, Haoran
    Abstract:
    With the introduction of high speed semiconductor power devices and the increased application of adjustable speed drives (ASDs) for efficient speed control of ac motors, there has been a growing number of costly motor-drive related process failures. It has been found that the high dv/dt and high switching frequency have...

  • A DSP controlled resonant active filter for current harmonic mitigation in three-phase power systems

    Creator:
    Ünsal, Abdurrahman
    Abstract:
    Power quality has become an important concern to both electric utilities and end users due to the increased use of non-linear loads in modem power systems over the past decade. Nonlinear loads inject harmonics into the power system and thus may lead to poor power quality and lower power factor....

  • Novel power conditioning circuits for piezoelectric micro power generators

    Creator:
    Han, Jifeng
    Abstract:
    Advanced low power devices promote the development of micro power generators (MPGs) to replace the batteries to power them. Due to the trend in decreasing integrated circuit (IC) supply voltages, power supply designers are facing more and more serious challenges. The objective of this research is to design a power...

  • A DSP controlled multi-level inverter providing DC-link voltage balancing, ride-through enhancement and common-mode voltage elimination

    Creator:
    Dai, Shaoan
    Abstract:
    With the development of high performance power electronic and semiconductor technologies, Adjustable Speed Drive (ASD) systems are increasingly applied in residential, commercial and industrial applications. Due to the advantages at higher power ratings, the three-level Neutral-Point-Clamped (NPC) Voltage Source Inverter (VSI) is being employed in industrial and traction applications, static...

  • Advanced propulsion systems for linear motion with high performance requirements

    Creator:
    Zhou, Xiaolin
    Abstract:
    Traditionally linear actuator applications are addressed by the use of hydraulic systems. The high maintenance cost and poor reliability will always be the most critical problem in the real applications. Benefited from both the high mechanical advantage of the roll screw and the simple structure of the switched reluctance motor,...
