synchronous buck converter

I have developed a synchronous buck converter, but there is something I don't understand. I am measuring the voltage drop across the low-side MOSFET. In my simulations, the voltage drop during conduction of the low-side MOSFET is negative (around -10 to -20 mV). However, real measurements show a...

I want to make an energy control system on a stationary bike. The main input comes from the generator and the secondary input comes from the 6V battery. The voltage from the generator ranges from 1-10V, so I need to make a buck converter to 5V as load power supply. before pedaling, the power...

Greetings all. can anyone help me with my synchronous buck converter? can some one give me some example arduino codes for ir2101 to drive my irf540? pls help, since I'm just learning about arduino thanks
