H-Bridge has been designed around IR2104 IC from international Rectifier. The board has been made mainly for DC-Motor application. The driver can handle load up to 8-10Amps. I have tested this board with 36V DC supply . The circuit uses N Channel IR540 MOSFETS from international rectifier. IR540 requires large heat sink for 10Amps load.  Board has shunt resistor to provide voltage proportional to current flowing through load. This can be later amplify and connect it to microcontroller.

Features

  • Motor DC Supply 36V DC (Screw Terminal Connector)
  • Logic Supply 12V DC
  • Load 8-10Amps (Screw Terminal Connector)
  • Header Connector for Inputs (7 Pin Header Connector)
  • On Board Shunt Resistor for Current feedback
  • PWM Frequency 10 to 20 KHz
  • Duty Cycle 0-99%
  • Logic Pins support 3.3V, 5V, 12V (Inputs and PWM)

    Hi there! Could you give me some advice? I would like to build simple DC motor speed regulator. I have 130V DC motor with encoder. I consider 2 options:
    a) use 2 relays for direction/ movement controll and PWM regulator for speed controll
    b) build full H-bridge (like this one) but for much higher suply voltage.
    I would like do it as simple as possible,wich one option you preffer? If the best is (b) could I replece just Q1-Q4 and C1 for 130V DC power suply? IR2104 is for 600VDC 🙂
    Best’s
