5.3 Power Supply
A 20kHz discontinuous flyback converter is used to generate the appropriate control voltages to operate the cell.
Power is derived from the cell's DC bus, via CN4 pins 4 and 1.

The above voltages are tested per TSI-131. The +5VDC (VCC) is regulated. The other power supplies are regulated
through their transformer secondary turns ratios. This provides a well regulated power supply with multiple isolated
auxiliary voltages.
