Abstract
An AC-DC converter includes a DC reference voltage generation unit that creates a DC reference voltage waveform based in part on a feedback signal. The AC-DC converter also includes an SCR firing unit that receives a variable frequency power output from the generator and that provides firing signals. The AC-DC converter further includes SCRs arranged as a positive bank of SCRs and a negative bank of SCRs. The AC-DC converter further includes a modulator unit that receives the firing signals and the DC reference voltage waveform, and that respectively outputs SCR gate signals to the SCRs. The AC-DC converter also includes a filter unit provided between the positive and negative banks of SCRs. The AC-DC converter also includes a voltage feedback path for feeding back the DC output voltage as the feedback voltage waveform.
