Abstract :
This paper is descried about a proposed scheme of a low-cost digital pulse width modulation (DPWM) control circuit for non-isolated DC-DC converter without A/D converter. Also, real-time PID control technique for DPWM is described. Some experimental results are revealed the proposed circuit and scheme. The purpose of this research is striking a balance between minimizing cost increase by digitalizing of the control circuit of DC-DC converter and speeding up the control circuit.
