Generalized Switched-Inductor Based Buck-Boost Z-H Converter

In this paper, a generalized buck-boost Z-H converter based on switched inductors is proposed. This structure consists of a set of series connected switched-inductor cells. The voltage conversion ratio of the proposed structure is adjusted by changing the number of cells and the duty cycle. Like the conventional Z-H converter, the shoot-through switching state and the diode before LC network ar...

Investigations on an Improved Soft Switched Clll Dc/dc Converter

A full-bridge CLLL DC/DC converter that uses an auxiliary circuit is proposed in this paper. The soft switching of lagging leg and auxiliary switches is achieved by the proposed circuit for providing reduced switching losses and high efficiency. The theoretical detail operation of the converter is presented. The proposed converter is verified using MATLAB simulation. Closed loop and open loop c...

A Modified Series Z-Source Inverter Based on Switched Inductors with High Voltage Gain and Reduced Voltage Stress on Capacitors

In this paper, a series Z-source inverter based on switched inductors cell is proposed for the first time. This inverter is able to increase the voltage gain in comparison to the conventional Z–source inverters in additon to solve the ST (shoot-through) state’s problems. In this inverter, the value of voltage gain is increased by increasing the number of used diodes and inductors in the switche...

Comparator Design and Analysis for Comparator-Based Switched-Capacitors Circuits

The design of high gain, wide dynamic range op-amps for switched-capacitor circuits has become increasingly challenging with the migration of designs to scaled CMOS technologies. The reduced power supply voltages and the low intrinsic device gain in scaled technologies offset some of the benefits of the reduced device parasitics. An alternative comparator-based switched-capacitor circuit (CBSC)...
