Improved power quality operation of symmetrical and asymmetrical multilevel inverter using invasive weed optimization technique
(
Elsevier
, 2022 , Article)
Low switching frequency pulse width modulation (PWM) technique for modulation and control of multilevel inverter in medium voltage high power applications is preferred in order to reduce the switching losses. In this ...
A Detailed Full-Order Discrete-Time Modeling and Stability Prediction of the Single-Phase Dual Active Bridge DC-DC Converter
(
Institute of Electrical and Electronics Engineers Inc.
, 2022 , Article)
The standard methodology to obtain the model of a power electronic converter is achieved by averaging the state-space dynamics of the converter's state variables. But the average of the transformer current is null over a ...
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. ...
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 ...
