The simulation control utilized pulse width modulation (PWM) signals to regulate the switches with specific duty cycles. A duty cycle value of 0.67 for the first stage of the converter. The duty cycle for the second stage was set to 0.75 to achieve high voltage amplification. The switching frequency was set to 20 kHz.<br \/>\n\u2022 For the predetermined parameters, an output current of 0.32A operates the converter in boundary mode. At this boundary point, the converter operates at a power of 150W. The shape of the inductor current can be observed in the three operating modes as depicted in Fig. 2.<br \/>\n\u2022 It can be observed that efficiency decreases as the converter\u2019s power increases. In other words, in CCM, the efficiency decreases. This is because at higher power levels, the losses in the converter\u2019s components also increase. These losses are proportional to the increase in converter power.<br \/>\n\u2022 Additionally, in DCM, soft switching occurs, resulting in a significant reduction in switch losses. This is what leads to a notable increase in efficiency between BCM and DCM, despite being at similar output power levels.<br \/>\n\u2022 The loss characteristics of BCM and CCM are similar, hence the similarity in their loss calculations.<br \/>\n\u2022 The efficiency trend for different output currents and power values is depicted in Fig. 3.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><div class=\"wpb_column vc_column_container vc_col-sm-4\"><div class=\"vc_column-inner\"><div class=\"wpb_wrapper\">\n\t<div  class=\"wpb_single_image wpb_content_element vc_align_center wpb_content_element vc_custom_1734292419157\">\n\t\t\n\t\t<figure class=\"wpb_wrapper vc_figure\">\n\t\t\t<div class=\"vc_single_image-wrapper   vc_box_border_grey\"><img loading=\"lazy\" decoding=\"async\" width=\"353\" height=\"283\" src=\"https:\/\/stei.itb.ac.id\/wp-content\/uploads\/17.-Riset-GK-Drb.jpg\" class=\"vc_single_image-img attachment-full\" alt=\"\" title=\"17.
