The blocking converter has a main power circuit (1) having the primary (21) of a transformer coupled to a supply (11) via an electronic switch (12). The secondary circuit (3) connects with the output (b, c) and has an auxiliary voltage (U4) applied to a regulating circuit (7) that limits the pulsed rate of the electronic switch (2) to an upper threshold value. The secondary circuit connects with a circuit (4) based around diodes (43, 46) and an RC circuit (41, 42) to generate the auxiliary voltage. |
