Explain Threshold Voltage

It simulates three phase simple PWM-180 degree conduction based inverter. Frequency and output voltage can be changed using slider gains block used.

This function quickly finds local peaks or valleys (local extrema) in a noisy vector using a user defined magnitude threshold to determine if each peak is significantly larger (or smaller) than the data around it. The problem with the strictly derivative based peak finding algorithms is that if...

This is a simple program written so the equations look like classical matrix equations and it solves the voltage out of the standard current driven loop filter. This is intended to be used in some future PLL analysis program, but it outlines the way to set up the equations, and solve them. There...
