“…Combination of PID and other controllers are also commonly found in literature [19], [20]. In literature, applications of buck converter are found in solar photovoltaic system [21], electric vehicle and hybrid electric vehicle [22], lead-acis battery charger system [23], and electromagnetic actuator array [24]. As the global trend is moving towards a sustainable future, thus a sustainable technology is demanding and these applications proven the importance of research to tackle the problem arises in DC-DC converter.…”
