This paper discusses a model for the harmonic analysis of full bridge diode rectifiers in Wireless Power Transfer Systems (WPTSs). The proposed model is based on an iterative algorithm which identifies the zero crossing of diodes currents, including the threshold voltage, the state-dependant differential resistance and the parasitic capacitance of diodes. The algorithm has been solved in MATLAB and...
Many devices need DC source with low ripple for normal operation. Three-phase bridge rectifiers are most commonly used as the base unit in the source. A simulation model built in MATLAB/SIMULINK is used to analyze the operating of DC source under unbalance mains. The simulation results characterize quality of output voltage versus unbalance of phase voltage.
Most of the work is based on dq model of the machine; simplifications are made on SERD such as ignoring the injected harmonics to the system by rectifier/inverter, neglecting the overlap angle of the rectifier. The harmonic analysis of drive has been studied, the comparison of the harmonic contents of key drive waveforms over a wide range of operating speeds based on total harmonic distortion (THD)...
Along with much request of green electrical source, it is more and more important to reduce its disturbance to electrical network. High-frequency PWM rectifier can adjust output voltage and make input current near to sine wave efficiently, but there are disadvantages such as high cost, high switch cost and low efficiency especial in high-power field. At high-power rectifier field, multi-pulse rectifier...
This paper introduces the model of linear generator in 3 phase analysis and in dq transformation. The linear generator is used to compare the synchronous generator because the source of the input is changing from torqueto the force. As known, force flows along the direction of the moving object. This linear generator model will use speed as the moving source to generate electricity at the output terminal...
Three-phase high-power rectifier has widely applied to electromotor and high-power AC-DC transformation, but there are many problems such as many harmonic waves and low power factor about high-power rectifier. Along with much request of green electrical source, it is more and more important to reduce its disturbance to electrical network. High-frequency PWM rectifier can adjust output voltage and...
Taking the three-phase uncontrolled diode-bridge rectifier of a certain style armored vehicle's power supple system as research object, a practical method to calculate the harmonic amplitudes of rectifier's DC-side output current is theoretically analyzed with the detailed calculation formulas are given.

In this paper, we present a case study of formal verification of analog and mixed signal designs using SPICE circuit simulation traces. We consider verifying safety properties of Full Wave Rectifier (FWR) using SPICE circuit simulation traces. We follow the formal verification approach of where authors have used the SPICE circuit simulation traces for doing the formal analysis of the Analog and Mixed...
We present a case study of formal verification of full-wave rectifier for analog and mixed signal designs. We have used the Checkmate tool from CMU [1], which is a public domain formal verification tool for hybrid systems. Due to the restriction imposed by Checkmate it necessitates to make the changes in the Checkmate implementation to implement the complex and non-linear system. Full-wave rectifier...
