<![CDATA[In the field of electronics, the use of voltage sources with stable values and minimal fluctuations is crucial for the optimal functioning of electronic devices. Efficient voltage conversion is essential for the change of DC voltage levels to achieve higher or lower output. One of the most frequently used converter types is the buck boost converter. A buck-boost converter is a type of DC-DC converter that is capable of producing an output voltage that is either higher or lower than the input voltage, depending on the configuration and operational conditions. The effect of frequency and duty cycle on voltage ripple in Buck-Boost Converter is an important research topic to improve the performance of the converter. The test results of the Buck Boost Converter with Duty Cycle exhibited a range of voltage ripple values, varying from 0.04 V to 13.51 V, when an input voltage of 17 V and an output of -12 V were employed. At a Duty Cycle of 100%, the converter demonstrated the smallest voltage ripple, while at a Duty Cycle of 80%, the largest ripple value was observed. At frequencies between 20 kHz and 120 kHz, with the same input and output voltages of 17 V and -12 V, the smallest voltage ripple at 120 kHz is 1.09 V, while the largest is 6.24 V at 20 kHz.]]>
