Pemodelan Fuzzy Logic Control untuk Pengendali PWM pada Buck Converter
Jurnal Nasional Teknik Elektro dan Teknologi Informasi, 2016 Recently the switching mode used in a buck converter is controlled by pulse width modulation (PWM) which has relatively higher efficiency compared to a linear power supply system. In general, there are two problems that often occur in the buck converter,
