Title:
ELECTRONIC POWER SWITCH
Document Type and Number:
WIPO Patent Application WO/2018/009747
Kind Code:
A3
Abstract:
In accordance with aspects of the present invention, a power control circuit includes a MAIN window comparator circuit providing a MAIN signal; an AUX window comparator circuit providing an AUX signal; a state machine receiving the MAIN signal and the AUX signal; a MAIN slew circuit coupled to drive a MAIN switch, the MAIN switch coupled between MAIN and an output; an AUX slew circuit coupled to drive an AUX switch, the AUX switch coupled between AUX and the output; wherein the state machine operates to continuously activate either the MAIN switch or the AUX switch according to the MAIN signal and the AUX signal such that the output is continuously coupled to either a MAIN input or an AUX input with minimum disruption to output voltage, input and output capacitance inrush currents or reverse conduction. What really makes the circuit unique is it is combined with an adjustable forward biased rectification circuit for each channel of MAIN and AUX.
