The Input Circuit converts 110VAC or 220VAC to an unregulated 300VDC. |
| • |
The unregulated 300VDC is chopped by The Power Switches. The chopped waveform
passes through Transformers T3 and T4. |
| • |
Rectification and Filtering converts the chopped waveform on the secondary of T4
into the desired DC levels of +/-5V and +/-12V. |
| • |
Control Circuitry closes the loop between input and output. Control provides the base
drive signals for the power switches and monitors power supply health. |
