Microprocessor controlled PWM inverters for UPS applications
thesis
posted on 2018-01-19, 12:29 authored by Muhammad Z.U. KhanThis thesis describes the implementation of microprocessor controlled single-phase and
three-phase inverters for UPS applications. A carrier frequency of 18 kHz is employed in
both cases, and the PWM pulses are generated directly by the microprocessor using the
regular-sampled symmetric PWM strategy. Single-edge modulation as well as double-edge
modulation has been implemented for single-phase and three-phase systems. Since in
general, software implementation of PWM strategies require precalculated pulse width
values, a scheme is proposed which enables the large quantity of such data to be handled
efficiently. The scheme involves the use of a small program for calculating and
transferring the data to the memory of the controller. [Continues.]
