摘要
系统采用STM32作为控制核心,利用电容和电感作为恒能量脉冲的传输模式,采用8421数字编码的方式来控制主电路的开通或者关断来实现负载消耗恒定功率的特性;通过电压和电流采样电路实时采集系统信号来保护主电路,采用LCD作为显示设备实时显示系统的各种信号。通过实验和仿真结果,验证了电路的可行性和可靠性。
The system uses STM32 as the control center,using capacitors and inductors as a constant energy pulse transmission mode. The 8421 digital coding way is used to control the main circuit on or off to achieve the load consumption of constant power characteristics. System signals are sampled in real time through the voltage and current sampling circuit to protect the main circuit. A variety of signals are displayed in real time on the LCD display device. The experiment and simulation results verify the feasibility and reliability of the circuit.
