I'll Assess the IBM 5150 Laptop electrical power provide While using the Apple II electrical power source in detail to show their commonalities and variances. They can be each off-line flyback energy provides with a number of outputs, but that is about all they've in widespread. Despite the fact that the Computer ability source makes use of an IC controller plus the Apple II works by using discrete elements, the Laptop electric power source utilizes roughly twice as numerous parts as being the Apple II ability source. While the Apple II electric power provide employs a variable frequency oscillator designed out of transistors, the PC power provide takes advantage of a fixed-frequency PWM oscillator provided by the NE5560 controller IC. The PC makes use of optoisolators to supply voltage responses to your controller, though the Apple II takes advantage of a little transformer. The Apple II drives the facility transistor instantly, whilst the PC employs a push transformer.
