IEEE transactions on industrial electronics (1982. Print), 2021
Four-switch buck-boost (FSBB) converter has the advantages of positive output voltage and low voltage stress of power switches. In this paper, a pulse width modulation (PWM) plus phase-shift control scheme is proposed to achieve zero- voltage-switching ...

Self-correcting PWM control for dynamic performance preservation in high speed on/off valve
Mechatronics (Oxford), 2018High speed on/off solenoid valve (HSV) has often been used for pressure and flow control in hydraulic systems, which require faster and more stable dynamic performance of HSVs to improve control preciseness.

Three-Level Quasi-Switched Boost T-Type Inverter: Analysis, PWM Control, and Verification
IEEE transactions on industrial electronics (1982. Print), 2018In this paper, a three-level quasi-switched boost T-type inverter (3L qSBT2I) is proposed. A new pulse-width modulated (PWM) control method is presented to reduce the inductor current ripple of the qSBT2 I.

PWM Controlled Proportional Equipment
Applied Mechanics and Materials, 2012The paper presents an experimental model of PWM controlled proportional pneumatic direction control valve developed by the authors, as well as the functioning of a pneumatic system that incorporates the original solution of valve. The main parameters that control the system can be settled using a software application developed for that purpose.

Experimental PWM Controlled Device
2019 International Conference on Industrial Engineering, Applications and Manufacturing (ICIEAM), 2019Using Pulse-Width Modulation (PWM) for LEDs powering, the frequency should be high enough so that the human eye does not notice flicker. High frequency also allows for a significant energy efficiency: most LEDs have a peak of the efficiency close to the maximum current allowed. Thus, the pulse switching on the current maximum with brightness adjustment

PWM Inverter Control by System Control Theory
IFAC Proceedings Volumes, 1990Abstract Systematical design method of pulse patterns of PWM(Pulse Width Modurated) inverter is proposed in this paper on the basis of system control theory. Merits of the design by means of system control theory are as follows: (1) Pulse patterns are designed in consideration of the load conditions and then, optimal pulse patterns are designed for ...

A Family of PWM Control Strategies for Single-Phase Quasi-Switched-Boost Inverter
IEEE transactions on power electronics, 2019This paper proposed a novel family of pulsewidth modulation (PWM) strategies for single-phase quasi-switched boost inverter (qSBI). By combining shoot-through (ST) mode in the inverter's switches and the turning-on state of an additional switch, the qSBI

Neural networks controlled PWM inverters
Proceedings of Power and Energy Systems in Converging Markets, 2002A high performance PWM inverter using neural networks controller is presented in this paper. Owing to the learning ability and robust capability of neural networks, the switching pattern of the PWM inverter can be optimized under the linear and nonlinear load conditions. Thus, a high quality and low harmonics sinusoidal output voltage is expected to be
