    This paper focuses on the concept of zero energy consumption building (ZECB). This paper has implemented the Thai mediation building, which designed and built using ZECB concept. The Thai mediation building requires zero energy from the grid because the main source of energy comes from the solar energy via photovoltaic system. Energy budget is used to calculate the relationship among energy generation, energy load, and energy storage, which is useful to construct any zero energy building.

    Power electronics laboratory on electromagnetic interference (EM) studies
    (2003-01-01)
    Khan-Ngem, Werachet
    This paper presents the simplified power electronics laboratory on conducted electromagnetic interference (EMI) based on the favorite and available tools and circuits. This laboratory is a part of power electronics subject on a third year undergraduate course. The aim of this laboratory is to introduce the effect of self-resonant frequency (SRF) of the passive components on conducted EMI. The switching characteristic of a switching device such as gate drive control, snubber circuit and parasitic of capacitors to ground are also included. Finally, students can have the concept of the EM1 diagnoses and analysis.
