| 20120087153 | INDIRECT D. C. CONVERTER WITH A SWITCHING FREQUENCY BEING DEPENDENT ON THE LOAD AND THE INPUT VOLTAGE AND A DEAD TIME DEPENDING ON THE SWITCHING FREQUENCY (Also Known as CONTROL CIRCUITRY, VOLTAGE CONVERTER, METHOD, AND COMPUTER PROGRAM) - A control circuitry for controlling operation of switches of a non-regulated DC-to-DC converter is disclosed. The converter comprises a transformer having a primary winding, which is arranged to be excited by means of electricity provided through the switches, and an output connected to at least one secondary winding of the transformer via a rectifier circuitry and suitable to provide an output voltage to a load circuitry. The control circuitry comprises measuring means arranged to determine a load caused by any load circuitry; and adjustment means arranged to adjust a switching frequency for operating the switches in response to the determined load such that the switching frequency is decreased for an increased load and vice versa. A non-regulated DC-to-DC converter, a method for controlling operation of switches, and a computer program are also disclosed. | 04-12-2012 |
