This is a design of a stable and reliable control and drive system of IGBT, according to the requirement of the dynamic harmonic filter. This design is centrally controlled by a 89C52 MCU and it mainly consists of 89C52 MCU, FPGA, touch screen, alarm circuit, drive and protection circuit, intelligent electrical energy sensor. It has main functions of collection of harmonic parameters of the power...
Description of PWM and sliding-mode controls implied to series active power filters is given. Structural schemas for both control methods are given. Simulation and experimental results are put as well as a comparison between the two control methods.
Set the date range to filter the displayed results. You can set a starting date, ending date or both. You can enter the dates manually or choose them from the calendar.
