摘要： In a double-ended isolated DC-DC converter, by using a main transformer and first and second pulse transformers, a first power switch of a primary side circuit and a first synchronous rectifier of a secondary side circuit are driven with complementary timing, and a second power switch of the primary side circuit and a second synchronous rectifier of the secondary side circuit are driven with complementary timing. A first turn-off edge signal and a first turn-on edge signal generated in a primary side control circuit are transmitted to the secondary side via the first pulse transformer so as to generate a driving signal of the first synchronous rectifier. In addition, a second turn-off edge signal and a second turn-on edge signal generated in a primary side circuit are transmitted to the secondary side via the second pulse transformer so as to generate a driving signal of the second synchronous rectifier.

摘要： A first drive control signal regenerating circuit outputs an ON timing drive signal at turn-ON of a main switch element, and a second drive control signal regenerating circuit generates an OFF timing drive signal at turn-OFF of the main switch element. A rectifying switch controlling switch element connected between the gate and source of a rectifying switch element is driven by an output of the second drive control signal regenerating circuit. An output of the first drive control signal regenerating circuit connects to the gate of a commutating switch controlling switch element, which connects to one end of an auxiliary winding, the other end thereof being connected to the gate of a commutating switch element. Accordingly, the rectifying switch element is directly controlled from the primary side.

摘要： A switching power supply unit includes an overcurrent protection circuit section and a latch-stop release signal output circuit section. The overcurrent protection circuit section performs an overcurrent protection operation for latching and stopping the switching operation of a main switch during an overcurrent state. The latch-stop release signal output circuit section outputs a signal, only in a predetermined latch-stop release period, for releasing the latch stop after a certain waiting time has elapsed from the time of the latch stop. This arrangement can virtually perform a hiccup-mode overcurrent protection operation at the time of overcurrent, and expands the scope of application of a switching power supply unit. Switching power supply circuits are interconnected by simultaneous starting connections. Switching controllers for the main switches are connected to match hiccup mode restart timings.

摘要： A DC-DC converter includes a reverse current detector for detecting a reverse current and a reverse current suppressor for increasing an input-output conversion ratio when a reverse current is detected. A choke coil increases the inductance in a current flowing region in which a very small reverse current flows and reduces the inductance in a current flowing region in which the current flowing is greater than or equal to that in a normal operation mode. In a reverse current flowing region in which the output current is negative, the DC-DC converter has unique regulation characteristics in which the amount of change in the output voltage relative to the amount of change in the output current is very large.
