Abstract: The invention relates to a control method and a controller for a DC-DC converter, such as a synchronous Buck converter, which exploits the principle of capacitor charge balance to allow the converter to recover from a positive and/or negative load current step in the shortest achievable time, with the lowest possible voltage undershoot/overshoot. The control method may be implemented by either an analog or a digital circuit. The controller may be integrated with existing controller schemes (such as voltage-mode controllers) to provide superior dynamic performance during large-signal transient conditions while providing stable operation during steady state conditions. The invention also relates to a method and a modification of a DC-DC converter topology that comprises connecting a controlled current source between an input terminal and an output terminal of the DC-DC converter; detecting a load current step to a new load current; modifying a duty cycle of the DC-DC converter; and modifying current through a parallel output capacitor of the DC-DC converter by controlling current of the current source. The methods and circuits provided herein are applicable to Buck converters and Buck-derived converters such as forward, push-pull, half-bridge, and full-bridge converters.

Abstract translation: 本发明涉及一种用于DC-DC转换器的控制方法和控制器，例如同步降压转换器，其利用电容器电荷平衡的原理来允许转换器从正，负负载电流步骤中恢复最短可实现的时间，最低可能的电压下冲/过冲。控制方法可以由模拟或数字电路来实现。控制器可以与现有的控制器方案（例如电压模式控制器）集成，以在大信号瞬态条件下提供优异的动态性能，同时在稳态条件下提供稳定的操作。本发明还涉及DC-DC转换器拓扑的方法和修改，其包括在DC-DC转换器的输入端和输出端之间连接受控电流源; 检测负载电流步长到新的负载电流; 修改DC-DC转换器的占空比; 以及通过控制电流源的电流来修改DC-DC转换器的并联输出电容器的电流。本文提供的方法和电路适用于降压转换器和降压型转换器，例如正向，推挽，半桥和全桥转换器。

Abstract: A patient support is provided comprising a frame including a deck support and a step deck positioned on the deck support. The step deck has an upper deck, a lower deck, and a side wall, the upper deck being spaced apart from the lower deck to define a recess of the deck. The step deck includes a first section and a second section configured to articulate relative to the first section. A mattress section support is positioned in the recess. A mattress has a mattress section supported by the mattress section support and the upper deck.
