Carrier-Based Discontinuous PWM Method for Five-Leg Inverter [PDF]

open access: yesIEEE Access, 2020
This paper proposes a rotation carrier-based discontinuous pulse width modulation (CB-DPWM) method for the five-leg inverter (FLI). The FLI based on two-level topology consists of 10 switching devices for driving dual motors.

A high-performance generalized discontinuous PWM algorithm [PDF]

open access: yesIEEE Transactions on Industry Applications, 1998
In this paper, a generalized discontinuous pulsewidth modulation (GDPWM) method with superior high modulation operating range performance characteristics is developed. An algorithm which employs the conventional space-vector PWM method in the low modulation range, and the GDPWM method in the high modulation range, is established.

± 180° Discontinuous PWM for Single-Phase PWM Converter of High-Speed Railway Propulsion System [PDF]

open access: yesEnergies, 2020
As high-capacity alternating current/direct current (ac/dc) power conversion systems, single-phase pulse-width modulation (PWM) converters used in high-speed railway propulsion systems adopt high-voltage Insulated-Gate Bipolar Transistors (IGBTs) as ...

A unified analysis of PWM converters in discontinuous modes [PDF]

open access: yesIEEE Transactions on Power Electronics, 1991
Three discontinuous operating modes of PWM (pulsewidth modulated) converters are considered: the discontinuous inductor current mode (DICM), the discontinuous capacitor voltage mode (DCVM), and a previously unidentified mode called the discontinuous quasi-resonant mode (DQRM).

Lifetime-Based Discontinuous PWM for Cascaded H-Bridge Converters

open access: yesIEEE Access
The cascaded H-bridge (CHB) is an attractive converter topology because it can provide voltage and power scalability. However, due to the difference in electrical and thermal characteristics of power devices, the CHB can be composed of cells with unequal

Development and Implementation of LED Street Lights with Bright and Extinguishable Controls and Power Converters [PDF]

open access: yesMicromachines, 2023
This study developed and implemented a driving power supply for light-emitting diode (LED) array streetlamps. The power stage was a quasi-resonant (QR)-flyback converter, its input power was the alternating-current power, and the LED array streetlamp was
