DC-DC转换器
摘要：
提供了电力转换器和转换电力的方法。在一个方面中，转换器包括：输入端，其用于接收具有输入电压值的输入电压；输出端；第一电压总线；中点；第一变压器，其具有初级绕组和次级绕组；第一电路，其耦合到输入端、耦合在中点和第一电压总线之间以及耦合到第一变压器的初级绕组；输出电路，其耦合到第一变压器的次级绕组并耦合到输出端；以及控制电路，其耦合到第一电路并被配置为控制第一电路以在第一变压器的初级绕组处提供AC电压，其中，该控制电路被配置为使用修改的三角波形来控制第一电路的开关。
摘要（英）：

Power converters and methods of converting power are provided. In one aspect a converter includes an input to receive an input voltage having an input voltage value, an output, a first voltage bus, a midpoint, a first transformer having a primary and a secondary, a first circuit coupled to the input, coupled between the midpoint and the first voltage bus and coupled to the primary of the first transformer, an output circuit coupled to the secondary of the first transformer and coupled to the output, and a control circuit coupled to the first circuit and configured to control the first circuit to provide an AC voltage at the primary of the first transformer, wherein the control circuit is configured to control switches of the first circuit using a modified triangular waveform.
