This paper briefly describes the concept of bi-directional DC/DC converter, it introduces the bi-directional DC/DC converter category, control technology and practical application. Bi-directional DC/DC converter is a vital component of the power electronic converter, in the case of two-way need energy flow, bi-directional DC/DC converter has important application value. As the development of science...
A LED intelligent wireless dimming system based on AVR microcontroller is designed in this paper. The system is part of a highly integrated drive power flyback power supply topologies, Using MAX16802 as a constant current LED driver, dimming part is ATmeage16 precise timing control microcontroller as the core, the use of AVR microcontroller timer to generate variable duty cycle PWM signal for the...
Developing a high performance control strategy for grid side PWM converter of DFIG wind power generation system is a significant point. In this paper, first, deriving and analyzing the mathematical model of grid side PWM converter, a vector control strategy is proposed. Second, the voltage vectors influence on the active power change and the reactive power change was analyzed, a direct power control...
This paper describes a novel switching signal generator for three-phase voltage source inverters. Unlike conventional space-vector pulsewidth modulation (SVPWM) which achieves three-phase input voltage by a combination of the basic space vectors, the proposed scheme produces optimal switching commands to minimize the filtered measure of quantization error. Under specific selections of the filter matrix...
