متن کاملA High Time Resolution Digital Pulse Width Modulator Based on Field Programmable Gate Array’s Phase Locked Loop Megafunction
The digital pulse width modulator (DPWM) is the crucial building block for digitally-controlled DC-DC switching converter, which converts the digital duty ratio signal into its analog counterpart to control the power MOSFET transistors on or off. With the increase of switching frequency of digitally-controlled DC-DC converter, the DPWM with higher time resolution is required. In this paper, a 1...
متن کاملGeneration of a High Resolution Digital Pulse-Width Modulator through Digital Control in General Purpose Field Programmable Gate Array
Pulse width modulators are the basic building block in digital control architectures of any power converters. The design of power converters requires a high resolution high frequency pulse width modulators (HRPWMs) in order to reduce the size and cost, improved dynamic behaviour and power density. Hence, this paper proposes a review of digital pulse-width modulation (DPWM) architecture that tak...
متن کاملAnalysis and FPGA Realization of a Pulse Width Modulator Based on Voltage Space Vectors
Pulse width modulation based on space vectors (SVPWM) technique has become the most popular and important PWM techniques for three phase voltage source inverters (VSI). In this paper, we present the analysis and realization of SVPWM for variable speed control of AC motor drives, employing Xilinx Spartan 3E FPGA device. The selection of zero vectors and space vector sequence are given and the po...
