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.
should not be too high as this is working at 300V and
could soon cause excessive losses.
