基于DSP控制的低压大电流开关电源设计
Design of Low-voltage High-current Power Supply Based on DSP Control
A low voltage and high current switching power supply based on DSP control is proposed. Using DSP control instead of traditional analog chip, and the main circuit, drive circuit, constant current control strategy and the dead time setting circuit are analyzed. A 3kW (15V/200A) power supply circuit is built to verify the feasibility in the laboratory, finally, the detailed experimental waveforms and data are proposed.
