用于双稳态电动摇臂闩锁的致动器控制系统

本发明提供了一种致动器控制系统，该致动器控制系统适合于提供对电磁闩锁组件的单导线控制，该电磁闩锁组件提供汽缸停用或气门机构系统中的可变气门致动。该系统适于控制电磁闩锁组件，该电磁闩锁组件需要用于闩锁的沿第一方向的DC电流以及用于解锁的沿与第一方向相反的方向的DC电流。该致动器控制系统包括反相DC/DC转换器和开关元件。在一些实施方案中，反相DC/DC转换器使用电容器来存储驱动反相电流的能量。在一些实施方案中，反相DC/DC转换器服务于电磁体的多个不同组。 An actuator control system suitable for providing single wire control of electromagnetic latch assemblies providing for cylinder deactivation or variable valve actuation in a valvetrain system. The system is adapted to control electromagnetic latch assemblies that require DC current in a first direction for latching and DC current in a reverse of the first direction for unlatching. The actuator control system includes an inverting DC/DC converter and switching elements. In some embodiments, the inverting DC/DC converter uses capacitors to store energy that drives the inverted current. In some embodiments, the inverting DC/DC converter serves a plurality of distinct groups of the electromagnets.
