Using Constant Current Control For Metal Purification
In the vast world of power supply applications, we can identify two main categories for regulating the power applied to the load. The first being ‘constant voltage’, where the control loop maintains a constant voltage to varying load current demands and the second, ‘constant current’ where the current is maintained constant to vary the voltage applied to the load.
Toshiba Introduces Low RDS (ON) P-ch MOSFETs for Mobile Devices
