【求助】如何把交流电压叠加在直流电压上
|
|
| 如何把交流电压（大概5-10V的正弦波）叠加在直流电压（400V以下）上？？请各位帮帮忙啊。 |

you may had to use a L-C circuit as one of two wires

| connecting the high voltage source in parallel. in addition, there must be a short switch across the L component. regarding both capacitance and inductance, you had to figure out their values, which function as a DC isolator for your AC voltage source. good luck. |

the work voltage of both the capacitor and
|
inductor are required to be over 400 V. the internal resistance of your AC source had to be known. the capacitor is used to isolate the DC source from the AC source. the inductor is used to inhibit the transient current which is incurred by opening and closing your voltage sources. you can consult a prof. in phys. dept. |
