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.

Curtis 1231C-8601 500A PWM DC motor controller teardown
Jay did a teardown of a Curtis 1231C-8601 500A PWM DC motor controller: The Curtis 1231c-8601 power board is relatively simple. It uses 18 MOSFETS in parallel to switch current from the motor- terminal back to the battery- terminal (the motor+ lead is already connected to battery+). The MOSFETs it uses are IXYS IXTH50N20 SP9536 chips. […]
