Now heres the funny thing, when I made the first half bridge and put in the first IR2110 to drive the two mosfets of that half bridge it worked fine, now I installed the other two mosfets in the other half bridge which has a separate transformer, I inserted the second IR2110 which is also driven from the same SG3525 from which the first one gets its signal, but now when I attempt to drive both only one of them works, the other one doesnt work at all. Both IR2110 are driven from an SG3525AN oscillator. Hi, folks So I have two identical half bridge smps, each uses two mosfets and one IR2110 which drives the mosftets, both IR2110 are powered from a single small transformer and rectifier/voltage regulator. SMPS circuit SG3525 and IR2110 integrated on the board in the primer drive MOSFETs IRPF450 transformer, the. 500W 1000W SMPS circuits schematic pcb diagrams all files: 500w-1000w-smps-circuits-half-bridge.rar. Half bridge method with different versions of the techniques used SMPS circuits test picture diagrams and photos seen in the application’s PCB file available control ICs TL494, SG3525 as a drive transformer and IR2110 used there are designs that applications design can assist you.
