Description
Summary:The problem of supplying power to a remotely located communications buoy is complicated by several factors including relatively high tow-cable resistance, variation of this resistance with temperature, and the wide range of power required. Several methods for supplying this power are evaluated, leading to a discussion of an automatically controlled power system. This method, employing a remotely located error amplifier, provides excellent regulation with a minimum amount of complexity at the buoy. Several advantages of this system include insignificant power dissipation at the buoy, small size, and automatic adjustment to either varying load requirements or changing system parameters. Several fault-finding circuits are employed to protect the system from short circuit, loss of feedback information, and overheating. (Author)
