The above VLSI components
will be designed in VHDL and simulated on the MAXPLUS+2
software from ALTERA inc. The design will then be implemented on the VLSI design kit and on our lab inverter.



COURSE A17: 3Æ VARIABLE FREQUENCY TRANSISTORISED INVERTER CONTROLLER


USES


AC power control applications using MOSFET, BJT or IGBT bridges to generate AC from DC as in:-
    1. Uninterrupted Power Supplies(UPS)
    2. AC motor control
    3. X-ray machines
    4. Electric furnaces
    5. Metal processing lines
    6. Welding machines

PREREQUISITES

        Knowledge of power electronics related to IGBT / MOSFET Inverters
        Course-A10- Design of Variable Frequency PWM Sine Wave generator
        Course-A1. Introduction to VHDL and VLSI design (I)

CONTENTS


        1. Frequency divider for internal timing and control.
        2. Bus interfacing logic for 8 and 16 bit CPUs for loading frequency and control data.
        3. Generating three Phase Potential waveforms, representing the R,Y and B phases
            (from material presented in Course A10).
