Claim 1
Independent Claim
194 words
A boost-converter with low losses comprising: an energy storing main inductor and a main diode connected in series between a first input terminal for a first voltage and a first output terminal for a second, higher dc-voltage, wherein a center point between the main inductor and main diode is connected to a common second input and output terminal via a controllable switching element; a control circuit for the controllable switching element, wherein the control circuit monitors the voltage of said first output terminal and controls on and off operation of the controllable switching element; an auxiliary inductor connected between the center point and a terminal on the controllable switching element in order to limit a reverse current in the main diode when the controllable switching element turns on; a zener diode and first and second diodes connected in series between the terminal on the controllable switching element and the output terminal for transferring energy stored in the auxiliary inductor towards the output terminal, and a first condenser for temporary storage of energy from the inductor, the first condenser being connected between the center point and a connecting point between the first and second diodes.
