Switch mode transformers with a half-bridge and full-bridge output configuration are also available. Switch mode transformers differ in terms of mounting configurations. Chassis-mounted devices use screw-down tabs. Disk-mounted devices use a simple rubber washer, a metal disc with a hole in the middle, and a sturdy clamping screw.
The input voltage or charging cycle produces energy which is stored in the inductor. The input energy or discharge cycle is then transferred to the output. Boost or step-up switch mode transformers convert a lower DC input voltage to a higher DC output voltage of the same polarity.
