The mechanism comprises a chassis installed on a ship or offshore operation platform, a support platform movably connected to the chassis, and three compensation components arranged uniformly around the chassis between the chassis and the support platform.

Compared with the prior art, the present invention enables the wave motion of the support platform to be flexibly compensated, making the compensation more accurate and stable.

Abstract: A switching converter includes a power circuit, a control circuit, and a regulation circuit. The power circuit regulates an output current through the load with at least one main switching transistor. The control circuit couples to the power circuit and controls on and off states of the at least one main switching transistor in accordance with a reference voltage received to control a minimum peak inductor current through an inductor. The regulation circuit provides the reference voltage to the control circuit and adaptively regulates the reference voltage in accordance with the input voltage and the output voltage. An effect of a duty ratio on an inductor current can be canceled out when the duty cycle changes due to fluctuations in the input and output voltages. An output current is kept approximately constant in a burst mode, thereby effectively reducing output ripple and noise.

Abstract: A DC-DC power converter employs a full bridge series resonant converter topology with a resonant tank and two transformers, one before and one after the resonant tank, to obtain a high voltage (e.g., approximately 300V, approximately 1500V or greater) output from a relatively low voltage (e.g., approximately 9V-16V) input, for instance an input from one or more battery cells. DC-DC power converter is operable to output high voltage (e.g., around 300V, 1500V or higher) short duration pulses (e.g., tens of nanoseconds or less). A burst mode control technique provides as good regulation characteristics at light loads. Instead of turning OFF the active switches during an OFF period, the switches are operated at a different frequency (e.g., higher frequency) during the OFF period than a frequency at which the switches are turned ON during the ON period. Auxiliary loads can also be supplied.

When the input voltage is greater than a predetermined voltage, the high-side driving unit controls the high-side switching transistor to be in a weak-conduction state or off state for a time period of an inductor current discharge phase.
