Abstract
A sinusoidal PWM type inverter using Gate-Turn-Off Thyristors and featuring a new instantaneous current control strategy is described. Its utilization as an interface for a utility-grid connected photovoltaic generator with maximum power tracking capability is explained, and computer simulated along with experimental waveforms are discussed. Its simple hardware circuitry and excellent characteristics make it suitable for a wide variety of applications, including AC motor drives.

Modulation of the Chopping Frequency in DC Choppers and PWM Inverters Having Current-Hysteresis Controllers

TL;DR: In this article, it was shown that the chopping frequency of a dc chopper converter depends on the square of the counter EMF of the load, which is a consequence of the fact that three phase currents must sum to zero, rendering one of the three current controllers redundant.
