Optoelectronic Feedback Control Techniques for Linear and Switch Mode Power Supplies
ثبت نشده
چکیده
The power supply designer is continually being pressured to provide units which have higher efficiency, better regulation, less EMI and RFI, and smaller size and weight, all at a lower cost. The solution to this problem is a combination of circuit topology, layout, and supply control. This application note will address output control techniques for linear and switch mode power supplies (SMPS). Specifically, it will cover control techniques using standard phototransistors and a new family of linear optocouplers.

Linear AC power supplies can be replaced by their nonlinear switching counterparts due to the lower voltage drops and higher efficiency and power density of switching-mode inverters. Multilevel cascaded H-bridge (CHB) converters are the preferred inverter structure because of modular configuration, control, and protection. The output voltage quality in CHB converters depends on the number of ou...
