ABSTRACT:
A low acoustic noise solution for snubber circuits is utilized for relieving spike noise under a low-load mode of a snubber circuit, and for avoiding electromagnetic interference under a high-load mode of said snubber circuit. A power transform device utilizing the low acoustic solution includes a power source node, a switch node, a ground node, a transformer, a third switching unit, a first spike noise snubber circuit, a first switch unit, a second spike noise snubber circuit, and a second switch unit. When the power transform device is under the low-load mode, the first spike noise snubber circuit is used to absorb power discharged from the transformer so that spike noise is relived. When the power transform device is under the high-load mode, both the first and the second spike noise snubber circuits are used to absorb power so that electromagnetic interference is relieved.
