Abstract
The disclosure relates to a system for implementing output voltage slope in current mode controlled power supplies wherein the slope is provided by feeding back the voltage analog of peak output current to an error amplifier which provides an error signal which is proportional to the difference between a reference voltage and the output voltage. The error amplifier includes a feedback path including a resistor from output to input to cause output voltage slope with increased current.
Claims12
A system for implementing output voltage slope in current mode controlled power supplies composed of plural power supply devices connected in parallel, comprising:
- (a) a power supply device having an input terminal and an output terminal for receiving an input signal at said input terminal and providing an output signal at said output terminal,
- (b) first circuit means coupled between said input terminal and said output terminal of said power supply device comprising control means under control of said input signal at said input terminal, and
- (c) second circuit means coupled between said output terminal and said control means of said power supply device comprising comparison means having first and second inputs and an output, said first input being coupled to a predetermined reference voltage source, said second input being coupled to said output terminal of said power supply device and a feedback circuit coupled between said output of said comparison means and said second input including an RC circuit and a resistor in parallel with said RC circuit.
