Question:

Will the electronic prawns, the general switching power supply can accept the emotional load?

Now I want to buy a larger power test power, about 1KW. I have no money, so I want to buy a switching power supply, so that you can save a lot of money, but do not know can not accept the emotional load

Answer:

Not necessarily So that the output if it is emotional load will affect the module loop So it may cause the switching power supply loop is unstable
Yes, the actual use of a lot. When using the attention, the output connected to a switch, stop, do not directly off the power, you must first disconnect the switch, to avoid inductive load current after the sudden change in the potential to damage the power supply. The above matters, even if other power supply, should be kept as far as possible.
If the switching power supply output DC, emotional / capacitive are not afraid. Direct current does not exist.
In general, when the switching power supply output power is less than 50% of the rated output power, with inductive load is no problem, more than 50%, the output of the loop will cause instability or even boot without output or burn high-power devices. This is what you use the structure of the switching power supply, mainly to see your switching power supply output equivalent filter capacitor capacity, if the capacity is large enough to make the output in any case always show capacitive resistance characteristics, no problem. If you specifically designed for the inductive load switching power supply, this time can be improved at the output. The following figure parameters are for 30V30A power supply and load. I rookie, for reference only, welcome to discuss.
