Dual Linear Power Supply Design

Linear regulators were the power supplies of choice until the 1970s for converting alternating current ac into a steady direct current dc for electronic devices.

Dual linear power supply design.

11 september 2013 hits. All circuits require some source of power to operate and the most convenient source of such power is an ac wall outlet. Basic linear power supply circuits design basic linear power supply circuits design details created. This series of tutorials explains in depth power supply design steps for the buck and the boost topology dc dc switching regulators supplemented by dedicated sessions on pcb layout and signal edge control for emi that apply to all switching regulators.

22044 in the current article we will turn our attention to the basic concepts of linear power supplies. Linear power supply design. Linear regulated power supply. Dual complementary when a positive and negative dc output of the same voltage is required a dual complementary rectifier is the best choice.

The switch mode power supply has a rectifier filter capacitor series transistor regulator transformer but is more complicated than the other power supplies that we have discussed. Linear power supply design information learn how to design your own high performance amplifier power supply. While this power supply type isn t used as prevalently today it s still the best choice for applications that require minimal noise and ripple. This tutorials series is split into 4 parts and provides details hints and tips which are useful even to the most veteran power supply designers.

Switch mode power supplies. In the case of a dual supply using a 25 0 25v transformer the worst case peak ac voltage is 80v but using diodes rated for 200v piv is wise. These power supplies are heavier and will have more audible noise from the transformer resonance than regulated linear power supplies.
