Latest Patents
One of his latest patents is titled "Static switch method and apparatus." This invention provides alternate current paths to a junction through different sets of gate-controlled SCRs coupled to the junction. The method begins by initiating a switch from an active set of SCRs to an inactive set by removing a gate signal from two parallel connected, opposite sense current-carrying SCRs. This process allows for the carrying of AC current in either direction. The removal of the gating signal is often triggered by an indication that one alternating current source is faulty, prompting a switch to a second source. Current is then sensed through the two SCRs of the active set to determine their current-carrying state. After determining the state, it is confirmed during a delay time period. If the current-carrying state of either SCR remains the same during this period, a gating signal is applied to a corresponding SCR in the inactive set to enable current flow. Once both SCRs in the inactive set are activated, the switch is complete. This method prevents inappropriate activation of the gate signals of an inactive switch by confirming the current during the delay period.
