Primary inductor because the inductor is charged during ON cycle of the switch For example, There are double ended flyback topologies with two switches. It is named as double ended because it contains two switches. Daniel Sepic of Pennsylvania hit the first ever home run. Wilt chamberlain.
A transformer is the obvious answer, however there are other devices, like Jacobs Ladders, inverters, buck-boost circuits, and not to forget the SEPIC circuit. Google that.

The power switch, Q3, is turned on to store an incremental amount of energy in the transformer. Current is forced through D6 into the output.
An equal amount of energy from the transformer charges the output capacitor and is delivered to the load. Regulation is achieved by controlling the duty factor and the incremental energy into the system. Both the power-switch and diode work in unclamped inductive switching; that is, the voltage placed on them is controlled to a large degree by the transformer leakage inductance and stray capacitance. When Q6 is on, the C26 positive terminal is held at ground, while the T2 one-to-one turns ratio places a voltage equal to negative Vin on the C26 negative terminal.
This means that the capacitor has the input voltage applied across it with the polarity shown. In this circuit, when the switch is turned on, an incremental amount of energy is stored in the primary inductance. Current flows in the inductor secondary and coupling capacitor C26 to equalise its charge.
When the switch is turned off, the voltage on the Q6 drain rises. A current flow from both primary through C26 and secondary through D9 is provided to the output.
This circuit has the advantage that both the Fet and diode voltages are clamped by the capacitors, so there is little circuit ringing. This topology has another advantage with power being simultaneously drawn from the input and delivered to the output, much like an auto-transformer. Since the power switches do not have to handle the entire power transfer, the circuit is more efficient. The table compares circuit stresses between the two topologies. This table assumes a very small inductor ripple current large inductance and ideal diodes.
It also assumes 50 per cent maximum duty factor for the flyback. These capacitors should have similar voltage ratings because they are each charged to the input voltage.
Both topologies have large AC ripple currents and must use low equivalent series resistance ESR capacitors.
For this design example, the SEPIC requires a s lightly larger output capacitance due to its larger duty cycle and longer diode off time, compared to the flyback. The table also shows Fet and diode voltage stresses for both circuits. However, it must switch an unclamped inductance and will have significantly higher voltage stress than the SEPIC Fet when this is factored in.
The flyback diode peak inverse voltage PIV starts with a larger voltage stress than that of the SEPIC, but also has an unclamped inductive-switching spike, making it significantly worse. In this example, the voltage stress makes a Schottky diode unacceptable for the flyback and forces the use of an ultra-fast diode with its higher conduction losses and correspondingly lower efficiencies.
Each circuit occupies a component area of just over three square inches. Except for the magnetics, both designs use similar power stage components. Different controllers were chosen for each design. In this application, it is set to a 75 per cent maximum. The flyback uses three input capacitors rated to handle the large AC-RMS requirement of the pulsating current generated by the Fet switch.
Generally, large-value, low-cost aluminium electrolytic capacitors work best compared to ceramics, which do not have the capacitance necessary to provide low-input ripple voltage.
This is a relatively low RMS current and capacitance value; a fairly easy requirement to meet.
