Lecture 19: Inverters, Part 3
We can realize more sophisticated multi-level inverters that can directly synthesize more intermediate levels in an output waveform, facilitating nice harmonic cancelled output content.
Duty Cycle
Voltage regulators, such as buck and boost converters, use duty cycle control. It contributes to the stability of the output voltage by altering the duty cycle based on the input
Duty Cycle Computation for Inverters
The duty cycle of an inverter is the fraction of time that the output voltage is at its peak value. It is an important parameter in the control of inverters, as it affects the output
Average-Value Inverter
The Average-Value Inverter block models an average-value and full-wave inverter. It computes the three-phase AC voltage output from inverter DC voltage by using the duty cycle information.
Discrete Duty Cycle Control for Single-Phase Voltage Source
Since steady-state error exists in the output voltage of a proportional-integral (PI) controlled single-phase voltage source inverter (SP-VSI), the bandwidth of

More importantly, with a duty cycle of 0.617 the peak voltage of the waveform is still in the permissible range, so devices depending on the peak voltage should work.
Basic Calculation of a Buck Converter's Power Stage
The first step to calculate the switch current is to determine the duty cycle, D, for the maximum input voltage. The maximum input voltage is used because this leads to the maximum switch
