摘要： One example includes an adaptive bus voltage auto-selection system. The system includes an input bridge configured to rectify an AC input line voltage to generate a DC bus voltage. The system also includes a voltage monitor configured to monitor an amplitude of the AC input line voltage and to generate an activation signal based on the amplitude of the AC input line voltage relative to a predetermined reference voltage. The system further includes an anti-series transistor switch pair that is controlled via the activation signal to selectively couple and de-couple the input bridge to an output stage to provide the DC bus voltage at a first amplitude based on a first state of the activation signal and at a second amplitude based on a second state of the activation signal, respectively.

摘要： In described examples of an interleaved forward voltage converter (400), a first inverter stage includes a first transformer (T1) having a turns ratio N1and a primary winding (410) having one terminal coupled to a source of input voltage (Vin) and another terminal coupled to a first switching transistor (Q1). A first secondary winding (412) for the first transformer (T1) has a first terminal coupled to a first terminal of a filter inductor (Lf), and a second terminal coupled to a first diode (Df1). A second converter stage includes a second transformer (T2) having a turns ratio N2 and a primary winding having one terminal coupled to the source of input voltage (Vin) and another terminal coupled to a second switching transistor (Q2). A second secondary winding (416) for the second transformer (T2) has a first terminal coupled to the first terminal of the filter inductor (Lf) through a second diode (Df2), and a second terminal coupled to a reference voltage source. A third diode (Ds) is coupled between the first terminal of the second secondary winding (416) for the second transformer (T2) and the second terminal of the first secondary winding (412) of the first transformer (T1).

摘要： A power conversion system (10) includes a converter (12) configured to convert an input voltage (VIN) to an output voltage (VOUT). The converter includes a switch (14) that is controlled in response to an activation signal (ACT) to provide current through an inductor (16). A transition mode controller (18) provides the activation signal (ACT) based on a measure of charge derived from current through the switch and based on the current through the inductor.
