In industrial world, many mass-produced products require high precision to maintain product quality. To support industrial performance, robots are widely used for high-speed repetitive tasks. The development of a Single-Input Dual-Output (SIDO) buck converter offers a flexible solution for efficiently managing power in robotic devices. The implementation of a PID controller in synchronous buck converters ensures stable output voltages within specified ranges. This study compares two topologies of synchronous buck converters - one without a controller and another employing a PID controller using the SIDO method - simulated using PLECS software. Simulation results with PID control closely approximate the desired voltage drop values. The synchronous buck converter with PID control is proposed as an effective system. PID controllers facilitate faster transient response to achieve desired output voltages with minimal overshoot and can reduce oscillations and instability that may lead to power wastage. In conclusion, this research affirms that a synchronous buck converter with SIDO configuration and PID controller is an efficient solution for applications requiring precise voltage and current regulation, while achieving optimal energy efficiency. © 2025 IEEE.
