The invention is suitable for the technical field of electronic circuits, and provides a charging conversion circuit, a vehicle-mounted charger and a vehicle-mounted all-in-one power conversion device, and the circuit comprises a chopper circuit module which is connected with a power input side and a drive circuit, and is used for receiving a first drive signal outputted by a DSP chip of the drive circuit, primary direct current of a power supply input side is converted into primary alternating current; the transformer module is connected with the output end of the chopper circuit module and used for converting the primary alternating current into secondary alternating current; the rectifying circuit module is connected with the transformer module and used for receiving the secondary alternating current, converting the secondary alternating current into secondary direct current and outputting the secondary direct current; the frequency and the duty ratio of the first driving signal are fixed values. According to the embodiment of the invention, since the frequency and the duty ratio of the first driving signal are fixed values, a DSP chip does not need to carry out loop algorithm control, the implementation is simple and reliable, the complexity of circuit control is remarkably simplified, and the number of components is reduced.

    本发明适用于电子电路技术领域,提供了一种充电转换电路、车载充电机及车载多合一功率变换装置,电路包括:斩波电路模块,与电源输入侧和驱动电路连接,用于接收驱动电路的DSP芯片输出的第一驱动信号,将电源输入侧的初级直流电转换成初级交流电;变压器模块,与斩波电路模块的输出端连接,用于将初级交流电转换成次级交流电;整流电路模块,与变压器模块连接,用于接收次级交流电并转换成次级直流电后输出;第一驱动信号的频率和占空比为固定值。本申请实施例由于第一驱动信号的频率和占空比为固定值,无需DSP芯片做环路算法控制,实现简单可靠,显著简化了电路控制的复杂度,并减少了元器件数量。
