This paper presents the modeling and simulation results of Z-Source Inverter based Static Compensator (STATCOM).The thirty bus system with and without STATCOM are modeled and simulated using the MATLAB software. The present work proposes Z-Source Inverter for the control of reactive power. Z-Source inverter would ensure a constant DC voltage across the DC link during the process of voltage. The...
Australia has seen a strong uptake of residential PV systems over the last five years, with small scale distributed generation systems now accounting for around 10% of peak capacity within the Australian National Electricity Market. As uptake further increases, there is concern about the ability of distribution networks to maintain reliability and power quality without requiring substantial add...
The power generation from renewable power sources is variable in nature, and may contain unacceptable fluctuations, which can be alleviated by using energy storage systems. However, the cost of batteries and their limited lifetime are serious disadvantages. To solve these problems, an improvement consisting in the collaborative association of batteries and supercapacitors has been studied. Neve...

In hybrid electrical vehicles (HEV) the battery, motor and inverter are the core elements of the electric drive train. In the inverter power semiconductors, usually packaged in a module, are used. To qualify such power modules for the use in HEV amongst others Power cycling and Thermal cycling tests have to be performed. These tests mainly ensure the reliability of the module regarding thermal ...
As demands for energy savings have increased in recent years, inverters are being used in a wider range of applications. Demands for lower cost, smaller size and higher efficiency will continue to further expand the range of inverter applications. However, as a trend toward eco-friendly products increases, some sort of measure is necessary to suppress the harmonics contained in the inverter inp...
Motomi Shimada Yoshihiro Miyaji Takashi Kaneko Keita Suzuki OVERVIEW: The first application for onboard storage batteries came with the commercialization of series hybrid drive systems that reduced the fuel consumption of diesel trains. Storage battery control has also been used for the absorption of regenerative electric power and to implement the regenerative brake with extended effective spe...
Mitsubishi Electric has developed new High Voltage Insulated Gate Bipolar Transistor (HV-IGBT) modules called the ‘R-Series’ with a high isolation package, which can be used with a wide operating temperature range from -50°C up to 150°C. The newly developed chip set achieves stable operation and high SOA capability over a wide temperature range. In addition the new package design is optimized f...
We have developed a new isolated AC/DC converter for electric vehicle on-board chargers. It consists of an AC/DC converter with Gradationally Controlled Voltage Inverter (GCVI AC/DC converter) and an isolated Zero-Voltage-Switching (ZVS) DC/DC converter, each of which is optimally controlled to convert in a highly efficient means. As a result, the new on-board charger has achieved a power conve...
This paper describes failsafe control methods for electric vehicles (EVs) with the failsafe structure in which front and rear wheels are driven independently. Based on failure-diagnosis results, the failsafe control is done by dividing fault states into two types, i.e. a slight failure such as a current or a speed sensor failure and a serious failure such as an inverter or a motor failure. For ...
