Pulse width modulation for current source inverters with arbitrary number of phases [PDF]
Scientific ReportsModulation techniques for current source inverters (CSIs) have traditionally been derived from those used for voltage source inverters (VSIs), with space vector modulation (SVM) and pulse width modulation (PWM) being the most popular. Among these, PWM is

Pulse-width modulated temporal interference (PWM-TI) brain stimulation
Brain Stimulation, 2023 Electrical stimulation involving temporal interference of two different kHz frequency sinusoidal electric fields (temporal interference (TI)) enables non-invasive deep brain stimulation, by creating an electric field that is amplitude modulated at the slow difference frequency (within the neural range), at the target brain region.Here, we investigate ...

Integer factor based SVPWM approach for multilevel inverters with continuous and discontinuous switching sequences [PDF]
Archives of Electrical Engineering, 2021 The most extensively employed strategy to control the AC output of power electronic inverters is the pulse width modulation (PWM) strategy. Since three decades modulation hypothesis continues to draw considerable attention and interest of researchers ...

Self oscillating pwm modulators, a topological comparision [PDF]
Conference Record of the Twenty-Sixth International Power Modulator Symposium, 2004 and 2004 High-Voltage Workshop., 2005 High precision control of the output voltage or current of a switch mode converter with fast response is required for a number of applications. Dependent on the type of application, the desired precision and transient response can be difficult, if not impossible, to achieve with standard pulse width modulation (PWM) control caused by limitations in ...
