DC-DC converter chips provide a regulated DC voltage output from a different, unregulated input voltage.

Power transformers convert power-level voltages from one level or phase configuration to another.

Switch mode transformers (switching transformers) are used mainly in switching power supplies and DC-DC converters.

Power supplies are devices that produce AC or DC power.

DC-DC converters accept DC input and provide regulated and/or isolated DC output in various applications including computer flash memory, telecommunications equipment, and process control systems

Medical power supplies produce conditioned outputs for medical devices, instruments, and equipment.

Power frequency converters take electrical input power at one frequency and voltage and provide electrical output power at a different frequency and at a different or equal voltage
