摘要
A programmable controller for switch-mode power converters that operates in a digital domain without reliance on operation software and the ability to vastly reduce or eliminate analog circuitry. The digital controller is re-programmable. In one embodiment, the substantially digital portion of the controller is a Field Programmable Gate Array that controls operation of the converter by generally converting an analog reference signal(s) (e.g. the voltage output) into the digital domain. The controller then can perform distributed arithmetic to generate a square wave signal capable of controlling at least a main switch of the converter. The present invention can, if desired, essentially eliminate analog controllers in power conversion systems such as switch-mode converters.
