Abstract

The present disclosure discloses a dual output energy conversion device, modulation method, and power supply device which can enhance the bus voltage boosting capability of the conversion device by using a first electric energy storage module, so that it can be used in a wider input voltage range. A first conversion output circuit and a second conversion output circuit are set, and voltage stress of all switching tubes is reduced to half of the direct current bus voltage, which can greatly reduce the system EMI of the conversion device in high-frequency applications, and improve the power conversion efficiency of the device. The dual output energy conversion device only needs to realize the control of one-stage power conversion, and has a simple control structure.
