Distributed secondary controller to ensure proportional sharing of reactive power in AC microgrid
(
Elsevier
, 2022 , Article)
In an ac microgrid, reactive power sharing accuracy is affected due to unequal values of interconnecting cable impedances. To resolve this issue, secondary controllers are used to compensate the effect of cable impedances. ...
Thermal analysis of Si-IGBT based power electronic modules in 50kW traction inverter application
(
Elsevier
, 2023 , Article)
Estimation of accurate IGBT junction temperature is crucial for reliability assessment. The well-known RC lumped approach can help predict junction temperature. However, this method suffers from inaccuracy while characterizing ...
Ultra high gain step up DC/DC converter based on switched inductor and improved voltage lift technique for high-voltage applications
(
John Wiley and Sons Inc
, 2022 , Article)
Voltage lift is a well-known technique to improve the voltage gain of the converter. A combination of switched inductor and the conventional voltage lift technique can be used to achieve high gain, but the semiconductor's ...
A Novel Modified Switched Inductor Boost Converter with Reduced Switch Voltage Stress
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Article)
Recently, switched inductor (SI) and switched capacitor techniques in dc-dc converter are recommended to achieve high voltage by using the principle of parallel charging and series discharging of reactive elements. It is ...
