Power converter
First Claim
1. A high duty cycle power converter (2) having a closed loop variable signal (12) current mode control characterised in that the variable signal (12) is changed by a derived signal (11) which is derived as a function of the difference between the desired duty cycle (7) and the measured duty cycle (6) and in which the output of the power converter (2) is used to clamp the voltage of the power converter (2) wherein a diode (23) is connected in parallel with an output inductor (21) of the power converter (2) to clamp the voltage of the power converter.

Abstract
A heavy duty cycle power converter (2) has current mode control in which the closed loop control is carried out by a controller (5) using a desired signal (11) which is a function of the difference between the desired duty cycle (7) and the measured duty cycle (6). This fluctuates current mode control without voltage feedback.
