Three Microwave Frequency Dividers Using Current Source/Sink and Modified Current Source Inverters

Protection Strategies for IGBT Current Source Inverters

An overview of overcurrent and overvoltage CSI faults is presented and strategies, how to protect a CSI equipped with IGBT power switches against these failures are developed and explained. The shown strategies and the related circuits are applicable at low expense and require only minor changes in the CSI and its control.

Mitigation Transformer Inrush Current Using Modified Transient Current Limiter

This study presents a modified transient current limiter (MTCL) for mitigation the inrush current of transformers. The MTCL is based on conventional transient current limiter (TCL), which, its configuration is modified to overcome the TCL drawbacks of operation. The proposed MTCL offers lower power losses and voltage/current THD during normal operation mode. It needs only one limiting reactor i...

RF Pure Current-Mode Filters using Current Mirrors and Inverters

In this paper the design method leading to the radio-frequency (RF) filters working in the pure current mode is shown. New active elements called current mirrors and inverters (CMI) are presented, a generalized variant (GCMI) is used for the design purposes, and a universal version (UCMI) is fitted to the filtering-circuit final solution. Initial autonomous circuits are derived from the full ad...

Current Regulator Instabilities on Parallel Voltage Source Inverters

Parallel inverters are often used to meet system power requirements beyond the capacity of the largest single structure. They have also been used to reduce harmonics, reduce PWM switching frequency and increase available output voltage or frequency. The type of parallel structure depends on the construction of the load motor, the most prevalent are dual three phase machines, split-phase machine...
