According to Outotec, grinding circuit efficiency is key to improving the overall performance of a concentrator, so good grinding-circuit control is of major importance.
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).
Off-line power supplies improve circuit efficiency while reducing heat dissipation, providing better power supply performance compared to linear or switch mode power supplies.
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 practice, realization of small values of load resistance come with a penalty of low circuit efficiency, power transfer to the useful load, that is, circuit losses effectively account for a portion of the load resistance.
To help maximize power supply circuit efficiency, the MOSFET controller functions as a proportional gate drive, which both protects against unnecessary MOSFET turn-off and reduces MOSFET turn-off propagation delay down to 15ns, thereby minimizing reverse current flow.
In shutdown mode, quiescent current is also low at 25 nA, helping to boost overall circuit efficiency.
The ZXGD3104N8's proportional gate-drive operation guards against premature MOSFET turn-off as the drain current decays, thereby maximizing circuit efficiency and ensuring body diode conduction losses are minimized.
90 or better to maximize circuit efficiency and minimize power consumption; constant current with extremely low ripple to eliminate thermal issues and visible artifacts; high efficiency (90 percent) to help luminaires meet Energy Star ratings; MTBF of more than 50,000 hours.
This results in low conduction losses and a substantial improvement in circuit efficiency - helping design engineers achieve regulatory requirements without the added complexity, such as synchronous rectification.
In shutdown mode, quiescent current is also extremely low at 25nA, helping to boost overall circuit efficiency.
Designed to maximize circuit efficiency and help achieve Energy Star product ratings, ZXGD3103N8 enables designers to reduce rectifier losses by up to 70% and increase power supply efficiency by up to 3.
