Product Definition

Differential Mode Choke
Used in switch-mode power supplies to reduce AC-line-conducted interference.

Common Mode Choke
Used in switch-mode power supplies to reduce the high-frequency electrical noise between any two supplies on out lines.

Output Power Inductor Used in the output inductor capacitor (LC) filter section of switch-mode power supplies to reduce the magnitude of ripple current on the output.

Flyback Transformer Stores energy. Energy stored in the primary winding during one portion of the switching cycles is transferred to the load by the secondary winding during the alternate portion of the switching cycle.

Uni-Polar Transformer Converts the supplied DC voltage and impedance level to another level. The current of uni-polar transformer flows simultaneously in both the primary and secondary windings during one potion of the switching cycle. The magnetic core of the transformer is reset with a clamp winding during the alternate portion of the cycle.

Bi-Polar Transformer Converts voltage and impedance level of the DC power to another level. The current of bi-polar transformers flows simultaneously in the primary and secondary windings. The bi-directional excitation delivers power to transformers and resets it.

Current Sense Transformer Controls circuits that change the input current to a different level of output current.

Driver Transformer Triggers the base of bipolar transistors or FET gates.
