Sola Basic Industries "forecast that minicomputer brands will be applying more transformerless switching regulators in 1972, for high effectiveness and decreased dimension and weight."
I will Assess the IBM 5150 Personal computer power offer with the Apple II electric power provide intimately to indicate their commonalities and discrepancies. These are both off-line flyback electricity supplies with a number of outputs, but which is about all they may have in prevalent. Although the Personal computer electrical power source uses an IC controller along with the Apple II uses discrete elements, the Laptop electric power supply uses roughly 2 times as quite a few factors as being the Apple II ability source. Even though the Apple II electric power provide takes advantage of a variable frequency oscillator crafted outside of transistors, the Computer system power provide makes use of a set-frequency PWM oscillator provided by the NE5560 controller IC. The Laptop takes advantage of optoisolators to provide voltage suggestions into the controller, when the Apple II employs a small transformer. The Apple II drives the power transistor directly, while the Laptop works by using a push transformer.
