摘要
The purpose of the paper focuses on developing the power supply to feed the laboratory power amplifier. Such a power supply contains one boost converter with power factor correction (PFC), one multi-output two-transistor flyback converter with two other output voltages feeding the power amplifier and with two other output voltages feeding the peripheral circuit of this power supply. Regarding the control methods used herein, the boost converter is controlled by L6561, whereas the two-transistor flyback converter is controlled by UC3845. In this paper, the mathematical derivation is firstly introduced, and secondly some simulated and experimental results are provided to verify the effectiveness of the proposed topology.
