Claim 0:
1. A control circuit for generating a primary alternating current (AC) voltage signal provided to a dielectric barrier discharge (DBD) disk of a three-dimensional printer, the control circuit comprising:
a switching regulator receiving a direct current (DC) voltage signal, wherein the switching regulator modulates the DC voltage signal based on a variable duty cycle to create a modulated DC signal; and
a modulation circuit in electrical communication with the switching regulator, the modulation circuit introducing a frequency component to the modulated DC signal, wherein the primary AC voltage signal includes a variable duty cycle and a set frequency, and wherein the frequency component introduced into the modulated DC signal is representative of the set frequency of the primary AC voltage.
