Abstract: A switching power supply is provided in two stages with the primary of the power transformer (18) being in the first stage and the secondary in the second stage. The first stage (Stage 1) includes an EMI filter (12) connected to the input of a rectifier (14). The output of the rectifier is connected to a self oscillating, half-bridge, resonant inverter (16) operating in open loop with the primary of the transformer (18) to provide isolation from the power source (10). Feed-forward control is used to compensate for line variations, providing very small output voltage variation compared with input voltage variation. In the second stage (Stage 2), the secondary of the transformer (18) provides an input to post regulator circuitry (20) including a PWM control circuit (34) to regulate the output current using the error signal representing the differences between the current sensed and the desired value.

The converter includes a primary side circuit, a first secondary side comprising first and second synchronous rectifiers that are adapted to alternately activate in synchronism with non-zero voltage level portions of the conduction cycle, and second secondary side circuit which polarity is reversed with respect to the first secondary side power circuit.

Abstract: A flyback converter (100) has a primary side (112) comprising a main switch (Q1) and a control device (116) and a delay circuit (110). The converter has a secondary side (114) comprising a drive circuit controlling a rectifying switch (Q4). The drive circuit comprises a first part including a first transistor (Q2), a first discharge diode (D2) and an on-node (D_ON) and a second part including a second transistor (Q3), a second discharge diode (D3) and an off-node (D_OFF). The control device is connected to the drive circuit via at least one drive capacitor (C1, C2) to the on- and off-nodes. The control device issues drive pulses to the main switch through the delay circuit and to the drive circuit. The drive circuit has a first mode of operation in a flyback phase, which is triggered when the main switch is turned off and the rectifying switch is rendered conducting. A second mode of operation is a forward phase, which is triggered when the main switch is turned on and the rectifying switch is rendered non-conducting. The flyback converter comprises few components and the main switch is efficiently prevented from conducting simultaneously with the rectifying switch.

Abstract: A method and system for providing synchronous rectification in power converters that includes controlling turnoff of a synchronous rectifier according to a timing signal representative of the switching time of a switch that is coupled to input of the power converter. Such a timing signal may be obtained directly or indirectly in various ways; for example, by sensing the voltage across the primary switch, or by sensing the drive voltage of the primary switch. Additional alternatives in an isolated converter having a transformer with a primary winding that is selectively coupled to the electrical power source includes sensing the primary winding voltage, for example, by directly sensing the primary voltage or by sensing the voltage across an auxiliary winding that is closely coupled to the primary winding.

Abstract: A resonant gate drive for an externally-driven synchronous rectifier circuit (18). The circuit (18) comprises a first and second first synchronous rectifier recovery switch (SQ3, SQ46), and a first and second sychronous rectifier recovery switch (SQ5, SQ6), and an at least one inductor (LR). The at least one inductor (LR) stores the energy from the capacitance of the first and second synchronous rectifiers (SQ1, SQ2) upon charging or discharging of the first and second synchronous rectifiers (SQ1, SQ2). The recovery switches (SQ3, SQ4, SQ5, SQ6) transfer the stored energy from the at least one inductor (LR) to the output terminal (22) creating a more energy efficient circuit.

Abstract: The invention relates to a power source with an arrangement for restricting a short-circuit current. The power source comprises at least a primary-side switch block (A), transformer unit (B) and a rectifier (C). The arrangement for restricting a short-circuit current is realized such that the operation of the rectifier (C) depends on a control from a pulse-forming part of the primary-side switch block (A) in such a manner that the control for at least one switching transistor (Q3, Q4) synchronized with a rectifier (C) control unit (8) is interrupted when the output current (Iout) of the rectifier (C) exceeds a certain limit value. In parallel with at least one switching transistor (Q3, Q4) in the rectifier (C) there is advantageously at least one other switch element to realize the secondary-side rectification in an overload situation.

Abstract: When a voltage is applied between the emitter and collector of a third transistor (Q103) to turn off first and third transistors (Q101, Q103), no voltage drop occurs across a third resistor (R103), and the second and third transistors (Q102, Q103) are turned off. When the first transistor (Q101) is turned on, a voltage drop occurs across the third resistor (R103), thus allowing the second and third transistors (Q102, Q103) to be on. The base current of the third transistor (Q103) is controlled to a minimum that can saturate the third transistor (Q103). When the current between the emitter and collector of the third transistor (Q103) increases, the collector currents of the first to third transistors (Q101-Q103) increases, and the voltage between the emitter and collector of the third transistor (Q103) decreases.
