Embodiment Construction
[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0020] see figure 1 and figure 2 , a DC / DC converter constant current mode control method, the high-voltage direct current of the whole vehicle is input to the DC / DC converter, the filter circuit in the DC / DC converter filters the high-voltage input direct current, and then enters the first-stage boosting circuit, Boost the voltage to a stable high voltage, then convert the direct current into alternating current through the full bridge circuit, convert the high voltage alternating current into low voltage alternating current through the transformer, and then rectify the low voltage alternating current into low voltage direct current through the synchronous rectifier, and then pass through the output filter circuit After the low-voltage output, the main controller controls the on-off of the full-bridge circuit through the conversion controlle...
