摘要： In order to toggle a clocked flyback converter circuit, which can be used in a heating circuit for heating a filament of an light source (50) for example, a current (l
s )
is monitored by a controllable switch (3) which is coupled to a primary side (1) of the flyback converter circuit. If the current (l
s ) reaches a predefined current value after the switch (3) has been deactivated, the switch (3) is actuated in order to toggle the switch.

摘要： An inductive power transfer (IPT) control method is disclosed for controlling the output of an IPT pick-up. The invention involves selectively shunting first and second diodes of a diode bridge to selectively rectify an AC current input for supply to a load, or recirculate the AC current to a resonant circuit coupled to the input of the controller. By controlling the proportion of each positive-negative cycle of the AC input which is rectified/recirculated, the output is regulated. Also disclosed is an IPT controller adapted to perform the method, an IPT pick-up incorporating the IPT controller, and an IPT system incorporating at least one such IPT pick-up.

摘要： A control methodology for a two-stage PWM DC-DC conversion system (16), with transformer-isolation, in which the converter circuit input voltage is compared to a set voltage (60) calibrated as a function of the desired output voltage and the maximum voltage conversion ratio provided by the second-stage converter (26). When the input voltage is above the set voltage, the second-stage converter (26) is controlled to provide both output voltage regulation during normal operation and output current limiting during over-current conditions (66, 76-82). However, when the input voltage is below the set voltage, the first-stage converter (24) is controlled to provide output voltage regulation with minor output current limiting, and the second-stage converter (26) is controlled to provide extended output current limiting independent of the input voltage (62-74).

摘要： A switching power supply unit is provided, in which circuit efficiency can be effectively improved compared with a usual case. Secondary windings of a transformer are configured of two sheet metals. Rectifier diodes in a rectifier circuit are connected between the two sheet metals. Inductance of a line between the rectifier elements and the secondary windings is reduced compared with the usual case where rectifier elements are connected between secondary windings and a wiring area, and consequently surge voltage to the rectifier elements is effectively suppressed. A plurality of diode chips configuring the rectifier diodes are preferably disposed at equal spaces along a winding direction of each of the sheet metals.
