Abstract:
1. A driver system comprising: a direct current (DC) voltage source; a first bi-directional DC-to-DC converter having a primary side coupled to the DC voltage source and a secondary side and comprising a control input configured to receive a first control signal configured to control conversion of a first voltage on the primary side of the first bi-directional DC-to-DC converter to a second voltage on the secondary side of the first bi-directional DC-to-DC converter; a second bi-directional DC-to-DC converter having a primary side coupled to the DC voltage source and a secondary side coupled to the secondary side of the first bi-directional DC-to-DC converter and comprising a control input configured to receive a second control signal configured to control conversion of the first voltage on the primary side of the second bi-directional DC-to-DC converter to a third voltage on the secondary side of the second bi-directional DC-to-DC converter; wherein the first and second bi-directional DC-to-DC converters are capable of boosting the first voltage; wherein the second control signal is a complement of the first control signal; wherein a voltage difference between the second and third voltages comprises an output voltage; wherein the output voltage comprises an amplification of the first control signal; a control system coupled to the first and second bi-directional DC-to-DC converters and configured to:
