<p>A hybrid relay is shown for switching power combining the advantages of a mechanical relay and a solid state relay. The mechanical relay has lower heat dissipation and can remain in more compact packaging for that reason. The solid state relay carries the load side current during the leading and trailing edges of the power cycle to prevent arc. To overcome the deficiencies in the prior art, the mechanical relay and solid state relay are connected in series on the control side of the device. An optional charge reservoir may be used to counter the bounce effects in the mechanical relays when switching high current loads.</p> |
