1. A voltage converter comprising:
a transformer comprising:
a primary winding; and
a secondary winding inductively coupleable with the primary winding;
a voltage summer comprising:
a first diode coupled to the secondary winding;
a second diode coupled to the secondary winding;
a first capacitor coupled to the first diode; and
a second capacitor coupled to the second diode;
an auxiliary voltage bus coupled with the voltage summer;
a controller configured to generate a pulse signal;
a gate driver integrated circuit (IC) comprising:
a voltage input coupled to the auxiliary voltage bus; and
a logic input configured to receive the pulse signal;
wherein the gate driver IC is configured to control a conducting state of a switching device based on a summed voltage and based on the pulse signal.
