A nonlinear average current control method using only dc-rail current for three-phase power-factor-corrected (PFC) converters was introduced recently. This paper discusses the effects of dead-time, sector synchronization, input voltage harmonic distortion and sensing delay on its control performance. A dead-time compensation scheme without additional sensing requirement that is suitable to the nonlinear...
The principle of photovoltaic grid-connected generation system is analyzed, and the research on PWM control strategy is done based on the power output side of photovoltaic grid-connected generation system. The direct current control strategy of photovoltaic grid-connected inverter is presented. The control fashion of applying fixed switch frequency and the feedforward compensation control of utility...
This paper presents in this study a control algorithm to compensate harmonic current and reactive power simultaneously in 3 phase, where 3-wire and 4-wire non-linear loads. If the utility voltage is distorted, active power filter (APF) allows similar level of distortion in the compensated source current. Therefore, the resultant source currents have the same waveform as that of the supply voltage,...
The DSTATCOM (distribution static synchronous compensator) is one of the custom power device that can regulate the voltage. DSTATCOM operated as a shunt connected static VAr compensator whose capacitive or inductive output current can be controlled independent of the system voltage. And the magnitude of compensated voltage is limited by characteristics of system and load. Compensation capability of...
