    • An alternative approach to solar and grid-connected hybrid electricity for homes and buildings in Malaysia 

      Rosnazri, Ali; Ismail, Daut, Prof. Dr.; Soib, Taib, Prof. Madya Dr.; Muhammad Irwanto, Misrun; Surya, Hardi (Universiti Malaysia Perlis (UniMAP)Centre for Graduate Studies, 2010-10-16)
      This paper presents the proposal of a solar and grid-connected hybrid electricity system for homes and also buildings. A new concept of using a DC motor and synchronous generator as an electromechanical inverter is ...
    • Development of simple multilevel inverter using voltage regulator IC 

      Rosnazri, Ali; Soib, Taib, Prof. Madya Dr.; Risnidar Chan Bahaudin; Dina Maizana, Maiz Ahmad; Syafruddin, Hasan (Universiti Malaysia Perlis (UniMAP)Centre for Graduate Studies, 2010-10-16)
      This paper presents the development of a simple 5- level multilevel inverter for low power applications that not exceeding 30W using the common LM350 voltage regulator IC. A microcontroller with dedicated program is ...
    • Harmonic performance of single phase transformer with DC biased 

      Syafruddin, Hasan; Ismail, Daut, Prof. Dr.; Soib, Taib, Prof. Madya Dr.; Dina Maizana, Maiz Ahmad, Ir.; Rosnazri, Ali; Nor Ashbahani, Ashbahani (Universiti Malaysia Perlis (UniMAP)Centre for Graduate Studies, 2010-10-16)
      Direct current (DC) flowing through the earthed neutrals of transformer windings causes a DC component in magnetizing current. Owing to nonlinearity, the waveform of this current is strongly distorted. A high enough ...
    • High side MOSFET driver design using discrete components for low voltage applications 

      Pungut, Ibrahim; Rosnazri, Ali; Ismail, Daut, Prof. Dr.; Soib, Taib, Prof. Madya Dr.; Dina Maizana, Maiz Ahmad; Risnidar Chan Bahaudin, Ir. (Universiti Malaysia Perlis (UniMAP)Centre for Graduate Studies, 2010-10-16)
      This paper presents the design of a high-side N-channel MOSFET driver using discrete components for low voltage applications, ranging from 3V up to 24Vdc operation. Special level shifting technique is used to increase the ...
