Abstract:
Conventional power plants such as PLTB or other traditional power plants that use generators require a voltage regulator to regulate the fluctuating voltage on the generator. Fluctuations in power generated by PLTB or other traditional power plants are challenging to maintain system stability. Based on this, the research in this final project was conducted to improve the battery charging performance on PLTB using a sepic DC-DC converter. This circuit has a battery charging circuit breaker that can be set at a particular voltage level to maintain battery quality and extend battery life. The sepic DC-DC converter can increase or decrease the voltage to a value that can be set so that battery charging can be done optimally. Testing was carried out by measuring the voltage and current produced by the generator on the wind turbine and measuring the output results on the sepic DC-DC converter and the ability of the entire system to charge the battery. The test results show that the sepic DC-DC converter can increase and decrease the voltage to a specific value according to the set value, namely at a voltage of 14 V. This circuit will turn off when the voltage from the wind turbine generator is below 4 V and turn back on when the voltage reaches 5.5 V
