Embodiment Construction
[0087] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0088] The parallel frequency shaking switching power supply provided by the present invention includes a switch driving module and at least two parallel power supply modules. The present invention adopts the frequency shaking technology between each power supply module, that is, at least two switch drive signals are sent by the switch drive module to drive the at least two power supply modules correspondingly, the switching frequency of the at least two switch drive signals is fixed, and the The switching frequencies of the at least two switch driving signals are not equal. The present invention can be implemented mainly in two ways, which are embodied by the first embodiment and the second embodiment respectively.
