Comparative analysis of DC DC converters in BLDC drive system using load prediction technique

Abstract

Power electronic converter utilization has surged significantly as a newlineresult of tremendous technology advancements and developments in newlinecommercial processes. In essence, converters are described as semiconductor newlinedevices used to condition or change power to proper levels. DC-DC converters newlineare a basic type of power electronic converters now on market and are newlinefrequently used in high power systems. To avoid the issues related to newlineoverloading scenarios, converters typically detect voltage and current. newlineAdditionally, improved line transient performance results from closed loop newlinecontrols that sense voltage and current. In order to feed inverter circuit and newlineexhibit switching mode regulation for motor, converters play a critical role in newlinedetermining performance of load. Due to their extensive applications and newlineimportance in both domestic and commercial sectors, power electronic devices newlinealso play a crucial part in motor drives. Subsequently, power supplies play a newlinesubstantial part in contemporary electrical drive systems and require a variety newlineof converters and controllers to perform effectively. Additionally, a variety of newlinecurrent and voltage sensing techniques are utilized to enhance an operation of newlinethe power system. In the proposed work, a new voltage and current sensing newlinetopology, along with a converter, is introduced for providing an effective motor newlinesupply. The input AC supply is converted into DC with the support of Diode newlineBridge Rectifier (DBR) for attaining DC supply. The voltage for DBR, however newlinerequires boosting to attain maximum voltage, which is achieved by means of newlineZeta converter. A DC-link capacitor is also used to manage a rectified voltage, newlinewhich serves as a power cord for energizing load. newline newline
