Also the secondary voltage
is not induced by the changing magnetic field of the primary, but by the wave front of the magnetic pulses travelling upwards.
In passive drivers a step-down transformer is used to reduce the line voltage and the secondary voltage
is then rectified and filtered with an electrolytic capacitor.
HSVM also has the same condition and therefore, to decrease the number of stages, a transformer whose secondary voltage
is twice of those for BVM and SPNVM could be used.
The insulation primary to secondary voltage
is 2.4 kV, a good signal for a less-loss full transformer.
It is not directly a power loss, but results in inferior voltage regulation causing the secondary voltage
not to be directly proportional to the primary voltage, particularly under heavy load transformers are therefore normally designed to have very low leakage inductance
The choice of the controller settings is discussed in some detail and examples of performance are given, combining the above remedial action with capacitor switching and secondary voltage
Conventional iron loss measurement uses Epstein frame and is based on the principle of applying a sinusoidal voltage to the primary (or the excitation) coil while measuring the induced voltage (secondary voltage
) and the leakage current.

It increases its secondary voltage
during coasting and braking phases, producing more electric power.
where [U,.sub.20] is the secondary voltage
reduced to the primary, corresponding to the idle running regime, [I.sub.10] is the complex expression of current [i.sub.10] passing through the primary winding in this case, called idle current.
