Controlling Power with SCR: Phase Angle vs Zero Crossing Mode

When controlling power with SCR-based designs, engineers are faced with the decision of what type of control mode to use; zero-crossing or phase angle control. In order to make the right decision, the design engineer must understand the advantages and disadvantages of both control modes as well as the attributes of his or her load. […]

SCR Control Goes Digital

SCR Control circuits and products have been around for decades. An industry-standard SCR controller typically consists of an SCR firing circuit, a phase-locked loop (PLL) or line synchronization circuit, and a means of controlling the firing angle of the SCR device, typically a 0-5V or 4-20mA analog input. While there are currently several industry-standard SCR […]
