System and method for supplying power at startup |
| 摘要 |
A system including a switch and a control circuit. The switch is configured to receive a first voltage. The control circuit is configured to, during a rising portion of a half cycle of the first voltage, (i) turn on the switch in response to the first voltage reaching a first value, and (ii) turn off the switch in response to the first voltage reaching a second value, where the second value is greater than the first value. The control circuit is further configured to, during a falling portion of the half cycle of the first voltage, (i) turn on the switch in response to the first voltage reaching the second value, and (ii) turn off the switch in response to the first voltage reaching the first value. |

1. A system comprising:
a switch configured to receive a first voltage; and a control circuit configured to
during a rising portion of a half cycle of the first voltage, (i) turn on the switch in response to the first voltage reaching a first value, and (ii) turn off the switch in response to the first voltage reaching a second value, wherein the second value is greater than the first value; andduring a falling portion of the half cycle of the first voltage, (i) turn on the switch in response to the first voltage reaching the second value, and (ii) turn off the switch in response to the first voltage reaching the first value. |
