Modelling of efficient heat sink for 3-phase inverter (PWM -IGBT based)  (English, Paperback, Sitangshu Sekhar Biswas)

In most appliances and devices, 3-phase (Φ) inverters are commonly used for the conversion of a Direct Current (DC) Voltage into Alternating Current (AC) voltage. For the purpose of conversion, a switching circuit is employed which grossly consists of two elements, namely the switch and the voltage modulation method. In this book, a 6-IGBT bridge circuit along with a Pulse Width Modulation (PWM) generator has been used. The average thermal loss of the inverter, constituting the thermal and conduction losses of the switches, is coupled with the respective loads using neural network simulation to give a building relation. Based on that, the heat sink is designed for effective heat dissipation. The thermal design is optimized on the basis of a parametric model, depending on a number of factors such as its size and shape, placement of switches, and structure of its fins, to keep a balance between the maximum temperature and the load applied. Overall, this Conjugate Heat Transfer (CHT) analysis involves three sections: Circuit Design, Neural Network Simulation, and Parametric Modelling of the Heat Sink.
