摘要： The invention relates to a method (300) for controlling a galvanically isolated DC converter (100). The DC converter (100) comprises a full bridge (110) for converting an input DC voltage (UinDC) into an input AC voltage (UinAC), a transformer (120) for converting the input AC voltage (UinAC) into an output AC voltage (UoutAC), and a rectifier (130) for converting the output AC voltage (UoutAC) into an output DC voltage (UoutDC). The method comprises the steps: determining (320) the duty cycle (D) of the full bridge (110); comparing (330) the determined duty cycle (D) with a duty cycle threshold value (Dth); calculating (340) an input DC voltage (UinDCcalc) according to an input current (I_in), the output DC voltage (UoutDC), a transformation ratio (U) of the transformer (120) and an adapted value (D_ad) of the duty cycle of the full bridge (110).

摘要： A constant on-time isolated converter comprising a transformer is disclosed. The transformer primary side connects to an electronic switch and secondary-side connects to a load and a processor. The processor connects to a driver on primary side through at least one coupling element and to the electronic switch. The processor receives an output voltage or an output current across the load generating a control signal. The driver receives control signal through the coupling element and accordingly changes the electronic switch ON/OFF state, regulating output voltage and current via the transformer, where the electronic switch ON/OFF duration is determined between the moment control signal changes from negative to positive and the moment it changes from positive to negative to achieve a high-speed response to load transient.

摘要： Power converters typically have unique circuitry for graceful start-up and to develop correct operating voltage biases. Typically this unique circuitry is incorporated into a primary-side “start-up” controller. This start-up controller can also be the primary means of control of the power converter once started. However, a secondary-side controller is typically needed for more exact output voltage regulation, duplicating circuitry already present in the primary-side start-up controller. During light-load or no load conditions, on and off switching of the gate driver is stopped when the secondary-side controller sends a standby code inhibit (disable) command to the start-up controller. When power needs to be sent to the secondary side of the transformer to charge a secondary side capacitor, the secondary-side controller sends an enable code command to the start-up controller where it is detect to allow the start-up controller to operate in a normal fashion with the secondary side controller.

摘要： Using two converters (1, 2) placed in a primary-side and a secondary-side and each configured as a single-phase full-bridge, and one single-phase transformer TR, a power conversion device converts DC power of a primary-side capacitor to which a primary-side DC voltage is applied, to DC power of a secondary-side capacitor to which a secondary-side DC voltage is applied, through a transformer (1, 2). A control device (10) sets a dead time Td1 for the converter 1 serving as a power-transferring side converter, to be equal to or less than a current-polarity reversal time Tcmtt, to thereby surely achieve zero-voltage switching.
