IGBT power supply is a single-phase H bridge inverter capable to provide current of ±12kA with 1MA/sec ramp rate. This paper describes performance requirements, ratings, inverter design calculations, multimodular topology, protections, fast control, symmetrical layout, bus bar engineering, and cooling requirement and test results.
Nowadays integrated circuits (ICs) lose its integrity because aged ICs are being recycled in the new products instead of fresh ICs. Replacing ICs potentially impacts the security and reliability of the electronic systems bound for military, financial and other critical applications. It is important to distinguish the aged ICs from the unused ones. The term aging implies the duration of IC in constant...
Multilevel inverters are replacing conventional two level inverters due to reduced dv/dt stresses, common mode voltages, and lower harmonic distortion. They are finding applications in motor drives, active filters and power conditioning. Cascaded Multilevel inverter is the most used topology among Multilevel Inverters, due to reduced number of components at higher voltage levels. Constant frequency...
This paper presents modeling and simulation of a single phase simplified eleven-level inverter (SELI). Multilevel inverter offers high power capability. Its performance is highly superior to that of conventional two-level inverter due to reduced harmonic distortion, lower electromagnetic interference and higher dc link voltage. The inverter is capable of producing eleven levels of output voltages...
This paper presents the design of Load side compensation topology of Dynamic Voltage Restorer using Z-source Inverter which is able to compensate voltage sag and swell at sensitive load terminals. Based on this topology, the DVR consists of uncontrolled rectifier for giving DC supply to Z-Source converter through DC link. Z- Source Converter based topology is proposed in order to enhance the voltage...
Multilevel inverter is emerging as a new breed of power inverter for high power applications, especially in FACTS controllers. This can develop high voltage with reduce harmonics through its own circuit topology. The power levels of the inverter are largely controlled by carrier frequency. For an air cooled design, the frequency is practically limited to 3 to 5 KHz. It is proposed to operate two inverters...
The Multilevel inverter is emerging as a new breed of power inverter option for high power applications, Especially for FACTS controllers. This can create high voltage and reduce harmonics by its own circuit topology. The power levels of the inverter are largely restricted by carrier frequency. For air cooled design the frequency is practically limited to 3 to 5 KHz for large inverters, hence to increase...
