Solar Inverter Design

Figure 1: Replacing a SJ with a SiC MOSFET, switching loss decreases significantly

Due to the ever-increasing demand for a clean and renewable source of energy, installing solar systems has accelerated significantly in the last decade. Contemporary solar applications require very highly efficient, power-dense and lightweight grid-tied inverters. Traditionally, IGBT has been the device of

Figure 1. A simple Zener regulator circuit

The subject of power supplies is potentially very broad and the application of resistors in power supplies is quite diverse. Here we will focus on power supply units (PSUs) designed for use in electronic appliances that nominally require fixed DC outputs ranging from just a few volts up to a few kV. Whether

Figure 1: I-V Characteristics of Normally Off GIT GaN and Conventional Normally On GaN

For more than thirty-five years, the power MOSFET dominated the power management systems due to its constant technological evolution from its device structure to its applications to circuit topologies. However, at the dawn of the new millennium, power MOSFET reached its theoretical limitations that it became un
