Perancangan Sistem Pengereman Regeneratif pada Sepeda Listrik dengan Menggunakan DC-DC Boost Converter

The increasing use of electric vehicles offers an alternative solution amidst the scarcity of fossil fuels and as an effort to reduce carbon emissions. However, energy optimization in electric vehicles, particularly in regenerative braking systems, remains a challenge. This study aims to design a regenerative braking system for electric bicycles utilizing a DC-DC boost converter. The system operates the BLDC motor as a generator during braking, allowing power to flow from the motor to the battery for charging, which is controlled by the DC-DC boost converter. This study focuses on designing a DC-DC boost converter as a power flow regulator controlled by a TLP250 MOSFET driver to maintain a stable output voltage and facilitate battery charging. The design involves implementing the BLDC motor as a generator, a three-phase rectifier to convert AC output into DC, and a DC-DC boost converter circuit based on the TLP250 MOSFET for voltage regulation. The system is managed by an Arduino Nano, which generates PWM signals to control the MOSFET switching. Testing results show that the DC-DC boost converter operates effectively, achieving a maximum output voltage of 54 V and an output current of 0.59 A at a switching frequency of 31.25 kHz. The system demonstrated an average efficiency of 83.4% under load variations of 47 Ω, 94 Ω, 100 Ω, 147 Ω, and 200 Ω
