    H bridge problems using IR2110

    Hello, I designed attached circuit to drive H Bridge. My generated input signals are in attached picture, duty cyce that I am using is 40% for each signal, 99 kHz frequency. As result I am getting really bad shape of signal on R9 resistor. I am no getting steep signal when I turning H bridge...

    How to improve efficiency of Full-Bridge SMPS?

    Hello, I am designing full-bridge SMPS with a linear voltage stabilizer in LTspice. When I was making measurements I discovered that the maximum efficiency of my power supply is around 30% at full load. Project assumptions: Input voltage: 230 AC Output voltage: 0 - 25 V DC Output current: 5 A...
