This paper proposes a Direct Active and Reactive Power Regulation of Grid-Connected converters using Sliding Mode Control approach applied to three phase PWM converters. The DPC-SMC controller regulates the DC-link voltage, active and reactive power-flows of the grid-connected converter. The proposed DPC-SMC strategy scheme calculates directly the required(More)
This paper presents a new approach of direct power control (FLC-DPC) strategy for to three phase PWM converters. In this novel strategy the fuzzy logic control (FLC) has been used. The converter lookup table is based on fuzzy logic rules, using the instantaneous active and reactive power errors and the position of grid voltage vector. The basic idea of(More)
This paper proposes the Fuzzy Direct Power Control (F-DPC), a new control approach applied to three phase PWM converters. The F-DPC controller regulates the DC-link voltage, active and reactive power-flows of the grid-connected converter. The principle of this control is based in fuzzy controller. The steady state and dynamic behavior of DPC and F-DPC are(More)
This paper presents a new sliding mode Switching Table direct power control for three-phase grid-connected voltage source converters (VSC). The proposed Direct Power Control (DPC) strategy employs a nonlinear sliding mode (SM) approach to directly calculate the required converter's control voltage so as to eliminate the instantaneous errors of active and(More)
This paper presents a control method which combines sliding mode approach of direct power control and operates with constant switching frequency. This novel scheme Sliding Mode Constant Switching Frequency Direct Power Control (SM-CSF-DPC) employs a nonlinear sliding mode control (SMC) approach to directly calculate the required converter’s control voltage.(More)
