Switched-Mode Power Converters
A new modeling approach for the spectral analysis of pulsewidth modulated (PWM) converters with independent inputs is developed. The key of this approach is to extend the Volterra functional series to nonlinear systems with multiple independent inputs. After formulating the state-space equations describing the dynamical behavior of PWM converters, the Volterra transfer function characterizing t...
متن کاملModelling of a Switched Mode Power Supply using VHDL - AMS – A Hardware Descriptive Language
This paper provides an overview of the VHDL AMS hardware description language for analog and mixedsignal applications like the switched mode power supply which is designed by describing the major elements or components of the system with the help of this hardware descriptive language and illustrating it using Hamster which is a simulation software for VHDL and Verilog Descriptive Language. Inde...
متن کاملEfficient Key Extraction from the Primary Side of a Switched-Mode Power Supply
In this paper we detail techniques that can be used to analyze and attack an AES implementation on an FPGA from the primary (i.e., external) side of a switched-mode power supply. Our attack only requires measurements of the duty cycle of the power supply, and then increases the signal-to-noise ratio (SNR) though averaging, deconvolution and wavelet based detrending. The result is an exploitable...
متن کاملMiniaturisation of combline filters for switched-mode power amplifier systems
This paper presents a coaxial combline filter for a class-S power amplifier for an operating frequency of 450 MHz. According to the measurement results, the filter provides a bandwidth of 26 MHz, an insertion loss of 0.55 dB, and a second pass-band only at 2.8 GHz. As the filter dimensions are crucial for the envisaged application, different ways to miniaturise the filter are proposed and their...
متن کاملMOSFET Failure Modes in the Zero-Voltage-Switched Full-Bridge Switching Mode Power Supply Applications
As the demand for the telecom/server power is growing exponentially, the need for higher power density increases each year. Increasing power density relies on less component counts, smaller reactive component size, and/or better system efficiency. Higher switching frequency leads to the smaller reactive and filter component size. Better efficiency, which reduces the heat sink or paralleled devi...
