Analysis of Switching Circuits Through Incorporation of a Generalized Diode Reverse Recovery Model Into State Plane Analysis

A 98.7% Efficient Composite Converter Architecture With Application-Tailored Efficiency Characteristic

“…With bidirectional power flow, this circuit is known as the Dual Active Bridge [13], and can be designed for control of its output voltage. If the secondary-side switches are passive diodes or synchronous rectifiers without active control, then this circuit is a simple DCX; the converter can then be optimized to achieve very high efficiency and soft switching at points neighboring the current where the transformer currents are trapezoidal [14]- [16]. If we denote the boost module conversion ratio as M boost , the system conversion ratio is M = N DCX + M boost .…”

“…Therefore the DCX module is able to operate at higher switching frequency, and ferrite core materials are employed for the DCX transformer and tank inductor. The tank inductor value is chosen to achieve zerovoltage switching of the MOSFET body diodes [14] and to minimize the transformer rms current at an intermediate power such that the system efficiency is optimized.…”

Optimization of spread-spectrum MSK sequences and passive, multi-resonant bandpass rectifiers for wireless power transfer with low electromagnetic interference

“…We perform a grid search using parallel simulations in the (a,,8,"/d parametric space for RL, where 1 RL = "2 (a"/lRl +, 8 (1 -"/d R2) (15) from (11) and (l3). From physical considerations, 0 � "/1, "/2 � 1.…”

“…Although there is a plethora of work analyzing resonant rectifiers including [13]- [15], which have a resem blance to parts of this bandpass rectifier circuit, together with off-resonance operation and especially with spread-spectrum, where the main difficulty in analysis is that in higher order topologies, multiple diodes are used with inputs that are relatively well-coupled and have outputs which are common. We propose a design method that uses a surrogate model for optimization.…”

Accurate Analytical Modeling for Switching Energy of PiN Diodes Reverse Recovery

“…SPICE models are accurate in modelling PiN diodes, although prior knowledge of all device parameters is required which may be hindered by the fact that some of them are not on the manufacturers' datasheet. Hence, although SPICE models are useful in understanding the PiN diodes' transient performance [17] and reliability [18], waveform based approaches can be a fast and reliable method of predicting the switching performance of PiN diodes under different conditions given a few initial measurements [19]- [22].…”
