Nowadays, most digital control for motion and power electronics systems are based on DSPs. This paper presents a FPGA-based digital control for a DC-DC converter. The main difference from DSP-based solution is that FPGA allows simultaneous execution of all control procedures, enabling high performance and novel control methods. The control algorithm has been developed using a VHDL language or CAD...
Traditional infrared detection system has small viewing field and low scanning speed, a new all-directional IRST system with high scanning speed is designed, which quickly images the whole spherical airspace on the infrared sensors by the reflector circumrotating in pitching and azimuth with high speed. The real-time processing system for high speed input images is constructed based on the processor...
For medium voltage high power grid-interfacing converters, the operating switching frequency is often around several hundred Hz to reduce the switching power losses. Therefore, to eliminate the even order harmonics and non-characteristic harmonics and to minimize the beat phenomenon, synchronous PWM techniques are desired for the high power low-switching converters. In this paper, a direct PWM synchronization...
