    • Core loss measurements of three phase AC induction motor 

      Ismail, Daut, Prof. Dr.; Anayet, Karim; Gomesh Nair, Shasidharan; Asri, N.; Syatirah; Muzhar, M. (Institute of Electrical and Electronics Engineers (IEEE), 2010-06-23)
      Core loss measurements at the field level for AC induction motor have been described. The standard requirements is the conventional no-load test to measure the “rotational losses” (sum of the core, friction & windage losses) ...
    • Experimental investigation of photovoltaic modules cooling system 

      Farhana, Z.; Mohd Irwan, Yusoff; Azimmi, R. M. N.; Nurul Razliana, Abd Razak; Gomesh Nair, Shasidharan (Institute of Electrical and Electronics Engineers (IEEE), 2012-03)
      The electrical efficiency of Photovoltaic (PV) cell depends on its operating temperature during absorption of solar radiation. It is well known that the power and efficiency of PV module usually falls at the rate of 0.5%/C ...
    • Maximum voltage angle optimization of uninterruptible power supply on three-level transformer-less photovoltaic inverter 

      Muhammad Irwanto; Mohd Irwan, Yusoff; Gomesh Nair, Shasidharan; Noor Syafawati, Ahmad (Institute of Electrical and Electronics Engineers (IEEE), 2012-05)
      his paper presents a new topology of three-level transformer-less photovoltaic (PV) inverter. In this topology, a 240V AC system is developed from a full bridge inverter circuit using PIC microcontroller (PIC16F628A-I/P) ...
    • Parameter determination of 0.5 hp induction motor based on load factor test - A case study 

      Ismail, Daut, Prof. Dr.; Gomesh Nair, Shasidharan; Muhammad Irwanto; Yanawati, Y.; Nor Shafiqin, S.; Mohd Irwan, Yusoff (Institute of Electrical and Electronics Engineers (IEEE), 2011-06-21)
      The load can influence the efficiency of the induction motor. Even if the load has higher or less load factor, it can reduce the efficiency of an induction motor by several percentage. By knowing this, it is important that ...
    • Photovoltaic powered uninterruptible power supply using microcontroller PIC16F628-I/P 

      Muhamad Irwanto, Misrun; Mohd Fareq, Abd. Malek, Dr.; Sasongko, P. Hadi; Gomesh Nair, Shasidharan; Mohd Irwan, Yusoff (Trans Tech Publications, 2014)
      Uninterruptible power supply (UPS) sits between a power supply such as wall outlet and devices to prevent undesired feature that can occur within the power source such as outages, sags, surges and bad harmonics from the ...
    • Relationship between the solar radiation and surface temperature in Perlis 

      Ismail, Daut, Prof. Dr.; Mohd Irwan, Yusoff; Safwati, Ibrahim; Muhammmad Irwanto; Gomesh Nair, Shasidharan (Trans Tech Publications, Switzerland., 2012-06)
      Statistical models for predicting the solar radiation have been developed. In any prediction of the solar radiation, an understanding of its characteristics is of fundamental importance. This study presents an investigation ...
    • Review on Malaysian and Thailand's perspective towards renewable energy 

      Gomesh Nair, Shasidharan; Muhammad Irwanto, Misrun; Mohd Irwan, Yusoff; Muhammad Fitra; Uda, Hashim, Prof. Dr.; Norman, Mariun (Trans Tech Publications, 2014)
      This paper presents a review on Malaysia and Thailand’s view on renewable energy mainly in the area of solar energy. It is based on a survey conducted on random subjects in Malaysia raging from different discipline such ...
