Desejo um controlador PWM que o usuário consiga regular a tensão de saída da placa através de dois botões + e -.
Deve ter também um botão de acionamento da corrente de saída.
O mais complicado nessa placa seria o controle de corrente a carga que seria conectada na placa pode consumir até 30A,
A placa será alimentada com baterias 18650 de 3,7v que a corrente dependendo da bateria utilizada pode ser entre 10A e 30A.
Segue imagem e algumas informações de uma placa similar que importamos atualmente.
Informações:
The NLPWM board is a variable voltage, all in one regulator(straight PWM) board where you actually select the output voltage(RMS) instead of just the duty cycle! It sports an on board 0.28", 3 digit, 7 segment display, on board fire/up/down switches and two N channel MOSFETs. Only 3 wires to the board!
Features and specs:
Lock/unlock
Input voltage = 2s-4s(Automatically detected)
Low voltage cutoff = LiOn + LiPo(user selectable)
Check unloaded voltage - Works like a standard voltmeter
Check loaded voltage - Keep an eye on battery sag + drop!
Output voltage selection increments = 0.1v
Output voltage min = 1v
Output voltage max = last loaded battery reading
Output voltage accuracy = 5%
Switching Frequency = 244hz
Dimensions = 19x83.5mm
Display Color = White(Blue and Red coming soon!)
Idle drain = 380uA
Recommended load current = 60A
NOTE: The board doesn't limit current or have any over current protection, so it should be added off the board. Be very careful working with high current!
If you're driving an inductive load, make sure to add a flyback diode, as the MOSFETs can be damaged.
