The application of the average current mode control (ACMC) to a new type of very efficient post-regulators is studied in this paper. This post-regulator, called series-switching post-regulator (SSR), has recently been proposed to improve the dynamic response series-switching of power factor correctors (PFC). The post-regulator exhibits very high efficiency due to the fact that only a part of th...

This paper provides an efficient control technique for the operation of a direct-drive synchronous generatorbased stand-alone variable-speed wind energy conversion system. The control strategy for the generator-side converter with maximum power extraction is presented. This control provides a constant output voltage and frequency which capable of delivering to variable loads. The main attention...

This paper investigates a novel direct torque control (DTC) for a sensorless interior permanent magnet synchronous motor (PMSM) based on a sliding mode technique (SMC). The speed and position of the interior PMSM are estimated online based on active flux concept. To overcome the large ripple content associated with the direct torque, a torque/flux sliding mode controller has been employed. Two ...

This paper deals with voltage control in a buck DC-DC converter. In fact, dynamic mathematical equations describing the principle behavior of above system have been derived. Due to nonlinearity established model, nonlinear algorithm is adopted. It based on sliding mode approach. To highlight performance latter, comparative study four algorithms carried out. The validity model and conceived are ...

Three-phase voltage source inverters (VSIs) with output $ LC$ filter are preferred topologies to provide and frequency support for islanded ac microgrids. This article proposes a finite-set quasi-sliding model predictive control (FS-QSM...

In this paper, a new variation of current mode control for high power factor Boost rectifier is presented. The general features are no input voltage sensing, no use of multiplier, and no inner current regulator. It therefore follows the same control structure as that of Linear Peak Current Mode Control (LPCM) and Non Linear Carrier Control (NLC) . However it implements a different equation for ...
