    摘要: A PWM controller of a DC-DC converter is provided. The DC-DC converter converts an input voltage into an output voltage and comprises an output inductor coupled between an output of the DC-DC converter and a phase node. A first sense circuit senses a signal from the phase node to generate a first signal corresponding to the input voltage. A second sense circuit senses the signal from the phase node to generate a second signal corresponding to the output voltage. A PWM generator controls a first transistor and a second transistor of the DC-DC converter according to the first and second signals. The first transistor is coupled between the input voltage and the phase node, and the second transistor is coupled between the phase node and a ground.

    摘要: A DC-DC converter including a Pulse Width Modulation (PWM) controller for converting an input voltage into an output voltage is provided. The PWM controller includes an error amplifier, a comparator, a PWM generator and a ramp generator. The error amplifier generates an error signal according to a difference between a reference voltage and the output voltage. The comparator compares the error signal with a ramp signal to generate a trigger signal. The PWM generator generates a PWM signal with a fixed turn-on time, wherein a frequency of the PWM signal is adjusted according to the trigger signal, the input and output voltages. The ramp generator generates the ramp signal according to the PWM signal, the input voltage and the output voltage.

    摘要: A new and improved submarine anchoring cable that includes an outer layer that comprises 20% to 80% polyurethane elastomer, 20% to 80% carbon fiber mixed at a certain ratio. The outer layer is compressed to wrap around an aramid fiber or an ultra-high-molecular-weight polyethylene (UHMWPE) fiber and a core of synthetic fiber rope with molecular malleability, e.g., nylon, nylon66, and the polyester rope. The rope is exposed in a form of a loop from both ends of the cable. Each loop has one or multiple layers of sheath made of aramid fiber, Kelvar fiber or UHMWPE fiber wrapping around the rope near a tie on each end to provide extra friction and withstanding strength. One end of the anchor cable is fixed to the offshore platform and the other end is fixed to each anchor to hold on to the offshore platform within a limited area defined by multiple anchors fastened to the offshore platform.
