Abstract
A relay circuit includes a relay and a current divider. The relay includes a coil and a contact. The contact is configured to switches on and off a supply of power to a load that is configured to operate with power supplied from a direct-current power supply through conduction of the coil. The current divider is connected between the contact and the load and configured to split a current supplied from the power supply to the load. The current divider incudes a resistor and a capacitor connected in series and grounded.
Claims14
A relay circuit comprising:
- a mechanical relay including a coil and a contact configured to switch on and off a supply of power to a load configured to operate with power supplied by a direct-current power supply through conduction of the coil;
- and
- a current divider connected between the contact and the load and configured to split a current supplied from the power supply to the load, wherein the current divider includes a series circuit and a discharge circuit, the discharge circuit and the series circuit connected to a first node interposed between the mechanical relay and the load and the discharge circuit and the series circuit connected to a second node which is grounded so as to be in parallel to each other, wherein the series circuit includes a first resistor and a capacitor connected in series;
- and
- wherein the discharge circuit includes a second resistor, the second resistor has a higher resistance than the series circuit.
