Abstract: The working process of booster circuit for electronically-controlled injector drive power was analyzed from the angle of the charge amount transfer and the mathematic expression between boost voltage recovery time and booster circuit control parameters before the saturation of inductor current was deduced under the discontinued current mode.Finally,the expression was proved to agree well with the test.For further analysis on boost circuit after the saturation of inductor current,it was found that the conversion efficiency of circuit decreased drastically.
