Abstract

The results of studying the power and noise parameters in a multichannel DC/DC converter are presented for battery-powered devices. This converter allows maintaining stabilized voltage in multiple outputs when the input voltage is lower, higher, or equal to the output voltage providing the maximum use of the battery charge while minimizing the size of external components. The features of switching processes are considered for transient operation modes. General-circuit simulation is used to rectify process parameters, to explore the sources of conversion losses, and to recommend selecting components ensuring optimum operational parameters and the best profile of control signals.

摘要

研究了电池供电设备的多通道 DC/DC 转换器中的功率和噪声参数的结果。当输入电压低于、高于或等于输出电压时，该转换器允许在多个输出中保持稳定的电压，从而最大限度地利用电池电量，同时最大限度地减小外部组件的尺寸。瞬态操作模式考虑了切换过程的特征。通用电路仿真用于校正工艺参数，探索转换损耗的来源，并推荐选择确保最佳操作参数和最佳控制信号分布的组件。
