Design of Single-Switch Inverters for Variable Resistance/Load Modulation Operation

Design of Single-Switch Inverters for Variable Resistance/Load Modulation Operation

Single-switch inverters such as the conventional class E inverter are often highly load sensitive, and maintain zero-voltage switching over only a narrow range of load resistances. This paper introduces a design methodology that enables rapid synthesis of class E and related single-switch inverters that maintain ZVS operation over a wide range of resistive loads. We treat the design of ClassE i...

Operation and Design of Multilevel Inverters

Design and Implementation of a New Switch-Diode based Single Source Multilevel Inverter Topology

Multilevel inverters are a new generation of DC-AC converters at medium and high voltage and power levels. These converters have made great strides in the use of industrial applications compared to conventional two-level inverters due to lower harmonic distortion, filter size, EMI and dv/dt. Besides these merits, some disadvantages can be mentioned such as more power electronics devices and com...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

A Modified Droop Controller for Parallel Operation of Single-Phase Inverters in Islanded Microgrid

Conventional droop control is a basic control strategy for power sharing in islanded microgrid applications. This strategy has several limitations, such as low transient response, frequency and voltage deviations. This paper presents a modified droop control method for the proper operation of parallel-connected inverters in islanded microgrid. The proposed method is able to improve transient re...
