| 摘要 |
<p>An electrical control circuit includes a first energy storage means adapted to store electrical energy in response to a potential source of a first polarity relative to a reference point in said circuit, thereby providing a first voltage of a first magnitude; a second energy storage means adapted to store electrical energy, without affecting said first energy storage means, in response to a potential source of a second polarity relative to said reference point, thereby providing a second voltage of a second magnitude; and means for electrically connecting said first and second energy storage means so as to provide an output voltage related to the sum of said first and second magnitudes. Four embodiments are presented with two embodiments arranged so that substantial voltage is supplied to a load only when said first and second energy storage means are connected by an electrical connecting means.</p> |
