Abstract

A solid-state relay (100), which includes a semiconductor switch (106) and a voltage boost block. The semiconductor switch (106) has a control input (124), which causes the semiconductor switch (106) to shift from an open, non-conducting position to a closed, conducting position when a voltage is applied to the control input (124), wherein the closed position is associated with a parasitic resistance of the semiconductor switch (106). The voltage boost block includes a boost converter (104) and a ground connector (114). A voltage output of the semiconductor switch (122) is electrically connected to a voltage input (108) of the boost converter (104). A voltage output (110) of the boost converter (104) is electrically connected to the control input (124). The ground connector (114) of the boost converter (104) is electrically connected to a voltage input of the semiconductor switch (106). The parameters of the semiconductor switch (106) and the boost converter (104), including the parasitic resistance and a voltage step-up ratio of the boost converter (104), are selected such that when the semiconductor switch (106) is in the closed position, a voltage at the voltage output (122) of the semiconductor switch (106) results in a voltage at the voltage output (110) of the boost converter (104) sufficient for application to the control input (124) at the semiconductor switch (106), to cause the semiconductor switch (106) to be maintained in a closed position in the absence of another control signal.
