Abstract
A charge collection device includes a capacitor, a first switch disposed between one terminal of the capacitor and a positive electrode of a DC power source, a second switch disposed between the other terminal of the capacitor and a negative electrode of the DC power source, a third switch disposed between the one terminal of the capacitor and a ground, a fourth switch disposed between the other terminal of the capacitor and the ground, and a charge collection circuit that has a fifth switch connected to the one terminal of the capacitor and configured to supply charge stored in the capacitor to an external circuit via the fifth switch.
Claims4
A charge collection device comprising:
- a capacitor;
- a first switch disposed between one terminal of the capacitor and a positive electrode of a DC power source;
- a second switch disposed between the other terminal of the capacitor and a negative electrode of the DC power source;
- a third switch disposed between the one terminal of the capacitor and a ground;
- a fourth switch disposed between the other terminal of the capacitor and the ground;
- and
- a charge collection circuit that has a fifth switch connected to the one terminal of the capacitor and configured to supply charge stored in the capacitor to an external circuit via the fifth switch.
A power collection method of a charge collection device, wherein the charge collection device comprises:
- a capacitor;
- a first switch disposed between one terminal of the capacitor and a positive electrode of a DC power source;
- a second switch disposed between the other terminal of the capacitor and a negative electrode of the DC power source;
- a third switch disposed between the one terminal of the capacitor and a ground;
- a fourth switch disposed between the other terminal of the capacitor and the ground;
- a charge collection circuit that has a fifth switch connected to the one terminal of the capacitor and configured to supply charge stored in the capacitor to an external circuit via the fifth switch;
- and
- a measuring circuit disposed between the third switch and the ground and that measures a voltage between the one terminal and the other terminal of the capacitor,
- the power collection method comprising:
- charging the capacitor by closing the first switch and the second switch and opening the third switch, the fourth switch, and the fifth switch;
- measuring a voltage between the one terminal and the other terminal of the capacitor using the measuring circuit by opening the first switch and the second switch and then closing the third switch and the fourth switch;
- and
- supplying charge of the capacitor to the external circuit by opening the third switch and then closing the fifth switch.
