Transformer parameters

Proprietary transformers are available, for example the

Pulse PAO367, Primary inductance: 24uH, Core: Pulse

PAO367, Turns ratio: 1:12, see Bill of Materials below. If

designing a transformer, bear in mind that the primary

current may be over an amp and, if this flows through

10 turns, the primary flux will be 10 Amp. Turns and

small cores will need an air gap to cope with this value

without saturation.

Secondary winding capacitance

should not be too high as this is working at 300V and

could soon cause excessive losses.
