Silicone touch switch filter loss Pf includes filter inductance loss and capacitance loss. If it is a continuous mode inductor, the main loss is the coil loss, and the core loss can be ignored. The capacitor has losses on the series equivalent resistance Resr. In the inductor continuous mode, the capacitor ripple current is small and the capacitor loss is also small. The entire filter loss is less than about 1% of the output power. If it is a flyback transformer, the Resr loss of the capacitor is greatly increased, and the filter loss is the capacitor loss. The rectifier circuit loss Pr includes the conduction loss caused by the forward voltage drop of the rectifier tube, the turn-off loss caused by the reverse recovery, and the buffer circuit loss to avoid the oscillation diode. Silicone Tact Switch Supply Because of its small size, long life, and light touch, it has been widely used in many fields such as home appliances. And with the continuous improvement of people's living standards, the replacement of these household appliances is getting faster and faster, and the quantity they need will become larger and larger, which is also a direction of great potential for us to be optimistic about its development prospects.
