u-Tum ratio=1:2:3
Vp-dielectric strength between coil windings with 60s test duration.
∫udt-Math product of volt-microsecond≈V1·tn(the value can keep unchanged in some frequency range).
V1-Input signal voltage (primary pulse voltage).
tn-Rated pulse width of the drive transformer, under related V1 and Fp.
V2-Output signal voltage (secondary pulse voltage).
RL-IGBT module or MOSFET equivalent resistance of control section.
Lp-Inductance of primary, f=1000Hz, V=0.3V.
Ls-Leakage inductance(measured when secondary shorted) f=1000Hz, V=1V.
Ck-Coupling capacity, f=1000Hz, V=1V.
