Design Guide
2.5 Transformer Design
The transformer is a key component in the power supply design. The starting point for the transformer design
is not always the same and is dependent on design constraints such as operating frequency or transformer
size. The transformer interacts with nearly all other design considerations. It is therefore difficult to design the
transformer in isolation. These interactions need constant consideration, and the transformer design needs
iterated to accommodate an acceptable compromise throughout the design of the power supply.
2.5.1 Material Selection
The bobbin, core and wire to be used in the transformer affect the overall design so need to be well defined.
They are often dependant on the power supply form factor so usually specified by the customer.
Select a transformer core and find the minimum cross sectional area of the core, Ae (other parameters, such
as volume, may be needed if core loss is to be calculated).
2.5.2 Winding Topology
The preferred winding topology is shown below.
Figure 8: Winding Configuration
Placing a single strand wire AUX winding next to the primary winding as shown helps to reduce the leakage
inductance between the primary and auxiliary. This helps to minimize the AUX voltage rise at full-load.
This winding arrangement also reduces the overall primary capacitance, which helps achieve higher
efficiency.
A copper foil shield is used to isolate the primary and secondary windings and to help with EMC.
2.5.3 Transformer Turns Ratio (N)
Ideally, the converter operation should reach boundary mode at the minimum input voltage VINREGMIN while
delivering full primary power, PPFL. VINREGMIN is determined from the low mains allowed by the input
capacitance (VDCMIN), with some margin.
Nopt I OUTCC VSCV VINREGMIN VCSMAX (1 K CTRLTOL ) 2 PPFL VCSCC VINREGMIN
2 PPFL VSCV VCSCC
PPFL is the full-load power at the primary of the transformer; VSCV is the voltage across the transformer
secondary at full power and minimum output voltage, taking into account the voltage drop across Dout as
calculated in section 2.2. VCSCC and VCSMAX are datasheet parameters. KCTRLTOL builds some design margin
into the current regulation point to take into account tolerances of components and controller parameters.
The maximum transformer turns ratio is limited by the voltage rating of the primary switch Q1:
