PFC power stage

PFC stage is required to shape the input current of the power supply and to meet the power factor and current THD norms such as IEC61000-2-3. In addition, the PFC stage also enhances system performance by reducing RMS input current, facilitating power supply holdup and improving efficiency of downstream converters.

Auxiliary power supply

Auxiliary power supply generally consists of a low power high voltage DC/DC converter for developing multiple isolated or non-isolated rails used to power various subsystems in the end equipment such as PWM controllers, gate drivers, sense and feedback components and in some cases a FAN. It can be made of multiple stages where the output from the main DC/DC converter could be fed to further low voltage DC/DC converters or LDOs. A typical aspect of the auxiliary power supply is its low standby power which is important in improving overall system efficiency.
