PWM basics and PWM drivers app note from APEX Microtechnology. Link here (PDF) PWM circuits are taking the same general course of development traveled by op amps and many other electronic functions. Concepts were brought to life using discrete components and were followed by modules, hybrids and then monolithics.
Using Apex Microtechnology’s power op amps for voltage controlled current sources (VCCS’s) application note, Link here (PDF) Voltage controlled current sources (or VCCS’s) can be useful for applications such as active loads for use in component testing or torque control for motors. Torque control is simplified since torque is a direct function of current in […]
Apex Microtechnology’s application note about programmable power supplies. Link here (PDF) The programmable power supply (PPS) is not only a key element in automated test equipment, but it is also used in fields as diverse as industrial controls, scientific research and vehicular controls. When coupled to a computer, it bridges the gap from the software […]
