Claim:
1. A driver system comprising: a direct current (DC) voltage source; a 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 bi-directional DC-to-DC converter to a second voltage on the secondary side of the bi-directional DC-to-DC converter; a capacitor coupled to the secondary side of the bi-directional DC-to-DC converter and configured to remove a DC offset of the second voltage; a reactive load having a first terminal coupled to the capacitor and a second terminal coupled to the secondary side of the bi-directional DC-to-DC converter; and a control system coupled to the bi-directional DC-to-DC converter and configured to: wherein the control system further comprises a digital controller configured to generate the reference signal from a plurality of digital values; wherein the digital controller is further configured to convert the plurality of digital values to an analog signal; and wherein the control system further comprises a filter configured to attenuate noise in the analog signal, wherein the noise is due to one of quantization and sampling.
