用于控制点火系统的方法和装置
摘要：
一种多次充电点火系统，该多次充电点火系统包括：火花塞控制单元，该火花塞控制单元适配为控制至少两个线圈级，以使所述线圈级连续通电和断电，从而向火花塞提供电流，两个线圈级包括：第一变压器(T1)，第一变压器包括电感耦合至第一次级绕组(L2)的第一初级绕组(L1)；第二变压器(T2)，第二变压器包括电感耦合至第二次级绕组(L4)的第二初级绕组(L3)，其特征在于，该多次充电点火系统包括：第一开关装置M1，第一开关装置M1电连接在电源高压侧与第一初级绕组的高压侧之间；第二开关Q1，第二开关Q1电连接在第一初级绕组与电源低压侧电源/地之间；第三开关，第三开关连接在第一开关和第一电感器的高压端的接头与第二初级绕组的低压侧和低压侧电源/地之间的点之间，并且还包括位于第二初级绕组的低压侧与所述点之间的第四开关以及位于所述点与低压侧电源/地之间的第五开关。
摘要（英）：

A multi-charge ignition system including a spark plug control unit adapted to control at least two coil stages so as to successively energise and de-energise said coil stage(s) to provide a current toa spark plug, said two stages comprising a first transformer (T1) including a first primary winding (L1) inductively coupled to a first secondary winding (L2); a second transformer (T2) including a second primary winding (L3) inductively coupled to a second secondary winding (L4); characterised in including first switch means M1 electrically connected between a voltage supply high side and the high side of the first primary winding, a second switch Q1 electrically connected between the first primary winding and the power supply low side supply/earth, a third switch connected between the junction of the first switch and high side end of the first inductor and a point between the low side of the second primary winding and low side supply/earth, and further including a fourth switch locatedbetween the low side of the second primary winding and said point, and a fifth switch located between said point and low side supply/earth.
