Title:

POWER SOURCE

Document Type and Number:

Japanese Patent JPH033674

Kind Code:

A

Abstract:

PURPOSE: To reduce a size and a weight by outputting the sum of the output voltages of a pair of parametric transformers.

CONSTITUTION: A power source has a pair of parametric transformers 10a-10b, and rectangular wave inverters 12a-12b are connected to the primary sides of the transformers 10a-10b, thereby energizing them with rectangular voltages V1-V2. Output voltages e1-e2 of secondary side have predetermined beat frequency with an output voltage e3 superposed thereon, and outputs through a rectifier 14, a reactor 15 and an inverter 16.
