| 摘要 |
An energy bypass circuit for connection between an energy source and a capacitance has first and second relays, a switch, and a resistance. The relays are operable so as to have a first state in which the energy source is not connected to the capacitance, a second state in which the energy source is connected to the capacitance via the resistance, and a third state in which the energy source is connected to the capacitance not via the resistance. The switch is operable, when the relays are in the third state, to enable additional charge stored by the capacitance to discharge via the resistance. |

1. An energy bypass circuit comprising:
a first relay having a first common terminal, a first normally open terminal, a first normally closed terminal, a first armature, and a first coil, the first armature being connected to the first common terminal and being arranged to connect the first common terminal to the first normally open terminal when the first coil is energised and to otherwise connect the first common terminal to the first normally closed terminal; a second relay having a second common terminal, a second normally open terminal, a second normally closed terminal, a second armature, and a second coil, the second armature being connected to the second common terminal and being arranged to connect the second common terminal to the second normally open terminal when the second coil is energised and to otherwise connect the second common terminal to the second normally closed terminal, the second normally open terminal being connected to the first common terminal; a resistance connected between the first common terminal and the second normally closed terminal; and a switch connected between the first normally closed terminal and the second normally closed terminal. |
