Texas Instruments recently released a book on the Fundamentals of Power Supply Design. It 's written by Bob Mammano, a power supply industry expert who is considered the father of the Pulse Width Modulation (PWM) Controller. It's a interesting mix of power supply fundamentals along with a history of the power supply industry of which Texas Instruments has played an important part in developing.   It's written for the beginner as well as the expert, covering power supply basics such as volt ...
Isolators are devices that minimize direct current (DC) and unwanted transient currents between two systems or circuits, while allowing data and power transmission between the two. In most applications, in addition to allowing the system to function properly, isolators also act as a barrier against high voltage.   For example, in this motor drive system, the isolated insulated gate bipolar transistor (IGBT) gate drivers level shift low-voltage signals from the control module to IGBT gate-d ...
