Family of saturable reactor assisted soft-switching PWM DC—DC convertors
A family of improved soft-switching pulse width modulation DC-DC convertors employing a saturable reactor assisted soft-switching technique are presented. These convertors use a small saturable reactor(s) to achieve efficient soft switching, and have advantages such as low switching and low conduction losses, wide load range and constant frequency ...

Saturable reactor assisted soft-switching full-bridge DC-DC power convertors
A new soft-switching converter technique is introduced which employs small saturable reactors and phase-shift modulation. This considerably reduces switching losses with no substantial increase in conduction losses. The proposed soft-switching concept and its modifications to full-bridge DC-DC power convertors are shown and discussed.

Switched-capacitor-convertors based on fractal design for output power management of triboelectric nanogenerator. [PDF]
AbstractOwing to the advantages of integration and being magnet-free and light-weight, the switched-capacitor-convertor plays an increasing role compared to traditional transformer in some specific power supply systems. However, the high output impedance and switching loss largely reduces its power efficiency, due to imperfect topology and transistors.

Time-domain analysis methods for switching convertors
Two algorithms are presented for a time-domain analysis of a switching convertor which is replaceable with a piecewise-linear system. One of these algorithms is for the transient state analysis and the other is for the steady-state analysis. Both algorithms use eigenvalue and eigenvector calculations of the matrix.

This paper introduces a simplified method for estimating switching energy losses in an IGBT device of a Voltage Source Converter (VSC) using Electro-Magnetic Transient (EMT) simulations. By considering the switching process as characterized by an equivalent circuit model of a unit cell that represents one leg of a VSC, equations are derived to evaluate
