  • A compact and high performance SC DC/DC buck converter 
    Baek, CJ; Kumarawadu, S [Conference-Abstract]
    A novel paralleling interleaved discharging (PID) approach is presented to reduce the output ripple and continuous input current waveform in step-down switched capacitor (SC). Theoretical analysis and the computer simulation ...
  • A novel active inrush suppression method for SC converter 
    Baek, CJ; Kumarawadu, S [Conference-Abstract]
    A new type of Inrush suppression circuit in SC buck converter is proposed. The method is realized by the hybrid of passive and active circuits. It adapts PIC micro controller to generate multi pulse to drive multi switches. ...
  • A novel morphin-based obstacle avoidance control algorithm for USVs 
    Jayendra, G; Kumarawadu, S; Piyasinghe, L [Conference-Abstract]
    This is an effort of employing good obstacle avoidance algorithms for unmanned surface vehicles (USV) which are already developed for unmanned ground vehicles (UGV). Previously developed Morphin algorithm is utilized for ...
  • Accurate attitude estimation of low-accelerating vehicles by the use of multiple low cost MEMS-Based IMUs 
    Dharmapriya, TDK; Kumarawadu, S; Piyasinghe, LP [Conference-Abstract]
    Inertial sensors and inertial measurement units (IMUs) are widely used in navigation support systems, autonomous vehicle navigation, and vehicle motion control process. Inertial measurement based attitude determination and ...
  • An Active monocular platform for intelligent vehicles: Design and simulations 
    Piyasinghe, LP; Kumarawadu, S; Jayendra, G; Dharmapriya, K [Conference-Abstract]
    Intelligent vehicles have to perceive their environment in order to navigate and avoid collision. This capability is also important in other applications such as mobile robot navigation, Automated Guided Vehicles (AGVs) ...
  • Fuzzy logic-based navigation of a boat 
    Jayendra, G; Kumarawadu, S; Piyasinghe, L [Conference-Abstract]

  • Proceedings of the 14th Annual Symposium 2008 (Pre Text) 
    Kumarawadu, S [Conference-Abstract]
  • Single switch dual output variable DC power supply 
    Kumarawadu, S; Palayangoda, LK; Fernando, MM; Hemathunga, HPGS; Premathunga, DSM [Conference-Abstract]
    Single Switch Dual Output concept has been introduced through an idea of controlling two DC power outputs by using only one switch. The controlling strategy is to control one voltage output by duty the duty of the PWM and ...
