By switching the transistor, either the voltage across the transistor is close to zero, or the current through it is close to zero, and therefore the dissipation cross-product is also almost zero. The conduction loss is not frequency dependent. It depends on the duty cycle. The way to reduce conduction losses is by lowering the ...
A larger device has more cells, hence a lower on-resistance (RON) and in turn a smaller conduction loss. However, more cells also mean higher junction capacitances, or larger charge storage (Q) at a given application voltage that translates to more energy loss in switching operations. As a...

Loss ∝ (switching frequency)*(switching time) Switching time is independent of frequency, therefore reducing the frequency increases the time between turn-off transitions for the MOSFETS and thus reduces cross conduction losses. Of course, the downside is that this will change the DCM inductance li...

Careful assessment is needed, however, as sinus bradycardia is not always a benign sign of excellent conditioning in the young population. Symptomatic bradycardia (along with other arrhythmias) has been associated with severe weight loss in patients with anorexia (Yahalom et al., 2013;Sall and Timp...

Switching power devices such as MOSFETs have two main loss components; switching losses and conduction losses. Conduction loss is dominated by current through the device and ON resistance of the device. Switching losses are dominated by gate charge of the switching device, gate voltage of the ...
