Power Supply Measurement and Analysis
Today’s efficient power converters demand less input power per watt of output, but they also demand more in terms of power supply measurements. Topologies are increasingly complex, and parasitics are everywhere, demanding careful comparison of simulations and measurements. Increasing switching frequencies make it harder to control EMI. And systems require a wide range of low-noise, fast-responding power supplies. You've come to the right place.
