I have 5 power supplies and need them to fire off in sequence to the frequency i provide.
For example i have a 5hz square wave with a 5hz gate. Every hertz i need to send the appropriate voltage to the transformer. 1hz 5v, second hertz 12v, third hertz 24v, fourth hertz 36v, fifth gertz 48v, reset during gate, repeat. Does that make sense? A square wave or step up voltage waveform that actually activates mosfets and steps up the voltage applied.
Any suggestions to start with? Have nano. Have plls, decade counters, andors, shift registers, and VCOs.
This setup uses a custom flyback transformer to test electrolysis experiments.
Since it's going into a transformer, I'd probably start by trying a high voltage PWM signal and vary the duty cycle to get the voltage I need. Not exactly a beginner project though.
Can you illustrate what you want with a couple of diagrams? Start with a schematic of how you envision this system; feel free to use 'black boxes' for the parts you're not sure what they'll be. Please include also a clear description of any parts/modules/equipment you've already decided will be part of the system. Furthermore, please explain clearly what the application is; i.e. how this variable/programmable power supply will function in an electrolysis environment.
Can you please draw a graph of the voltage output you need versus time, to clarify what you want?
Can you tell us what your project is?
For example i have a 5hz square wave with a 5hz gate. Everycycle i need to send the appropriate voltage to the transformer. first cycle 5v, second cycle 12v, third cycle 24v, fourth cycle 36v, fifth cycle 48v, reset during gate, repeat.
Can you please tell us your electronics, programming, arduino, hardware experience?
Start with relays! You can write the program to control the relays based on any signal you want. Since there is no current involved, the relay only has to have voltage rating.
chimed in I already had done it. Cheers.
