    Abstract: A switch assembly includes one or more solid state semiconductor switches configured to be disposed within a downhole pipe assembly. The one or more switches are configured to operate in a closed state to conduct electric current supplied by a power source disposed above a surface to pumps disposed beneath the surface to cause the pumps to extract a resource from beneath the surface via the pipe assembly. The one or more switches also are configured to operate in an open state to stop conducting the electric current from the power source to the pumps.

    Abstract: A direct current (DC) to DC power converter includes a first bus converter for converting a first DC bus voltage into a first high frequency AC voltage and a second bus converter for converting a second high frequency alternating current (AC) voltage into a second DC bus voltage. The DC to DC converter also includes a resonant circuit for coupling the first bus converter and the second bus converter and a controller for providing switching signals to the first bus converter and the second bus converter to operate the power converter in a soft switching mode. The controller includes a switching frequency controller for determining a switching frequency signal for the power converter based on a reference output current and a phase shift controller for determining a phase shift signal for the power converter. When the reference output current is lower than the a first load current value the switching frequency signal is maintained at a first switching frequency and the phase shift is determined according to the reference output current. Further, when the reference output current is above a second load current value the switching frequency signal is maintained at a second switching frequency and the phase shift is determined according to the reference output current. When the reference output current is between the first load current value and the second load current value, the switching frequency signal is adjusted according to a value of the reference output current and the phase shift is determined based on the switching frequency, the reference output current and perturbations in the output current.
