The goal of this study is to define the optimal PWM strategy adapted to a given variable-speed induction motor drive. A complete set of simulation programs performs steady-state and transient analysis of wave-forms. Some original PWM modes have been implemented on two digital modulators.
As the switching frequency of a dc-dc converter is raised from 100 kHz to 1 MHz, one would expect the energy storage elements of the circuit to be correspondingly reduced in size. If the circuit must meet input and output ripple requirements of the nature of MIL-STD-461B CEO3, however, the advantage of a higher switching frequency is significantly offset by the higher filter attenuation levels required...
A new control technique based on deadbeat control theory is proposed to obtain a nearly sinusoidal PWM inverter output voltage using only a voltage sensor. The closed loop sampled-data feedback scheme inherently results in very fast response to load disturbance and nonlinear load, producing low total harmonic distortion. Parameter estimation of the plant provides a type of self-tuning of the proposed...
