The determination of the ATM-SVI circuit efficiency based on the approaches proposed in the works [1, 13] is carried out, which include the following: to solve the problem of determining the optimal modes of the traction drive, four problems of the conditional optimization of the parameters of the traction drive must be solved (in acceleration modes [U.sub.op] = 1, regenerative braking mode [U.sub.op] = 5, maintaining mode of a given movement speed [U.sub.op] = 2.3).
With the module area [A.sub.module], it is possible to adjust the equivalent circuit efficiency [[eta].sub.circuit] to the module efficiency [[eta].sub.module]:
The power delivered to the wire, or the excitation circuit efficiency, can be written [10], [14]:
Boost converters with zero voltage switching (ZVS), have proposed with advantages of high frequency operation, ZVS switching and high circuit efficiency (Lin et al 2010; Lin et al 2009).
In general, a better tuning circuit efficiency is obtained with a lower CLF.
With circuit efficiency being taken into account, the output power [P.sub.out] of converter can be expressed as in (6).
The FETs offer the following features: low parasitic capacitance which reduces switching losses by at least 50% resulting in higher efficiency circuits; lower on-resistance to reduce conduction losses resulting in circuit efficiency gains; as well as excellent radiation performance.
In order to investigate what influence track line isolation has on track circuit efficiency, the dependency of sector five and three relay-end voltage ratio on isolation resistance [r.sub.i] was analysed at all the frequencies that are implemented (Fig.
With improved power circuit efficiency, the new BD recorders as well as the DRM-XW300 and DMR-XW100 DVD recorders consume only a 0.3W standby energy, the smallest in the industry.
