摘要： In a fly-back voltage converter that includes a transformer to transform a primary current to a secondary current and a switch serially coupled to the primary winding to switch the primary current in response to a control signal, a detection signal is produced by comparing the secondary current with two threshold values after the primary current is switched off to trigger the next on-time cycle of the switch. Once the secondary current is detected to be greater than a first threshold value, it is determined that the secondary current has been switched on, and until the secondary current is detected to be lower than a second threshold value, it is determined that the secondary current is to be switched off. The hysteresis range of the threshold values prevents error detection of the secondary current.

摘要： A plurality of switches, an inductor and two capacitors are configured to be a boost-inverting converter. To operate the converter in a boost-inverting mode, a control apparatus and method switch the switches such that the inductor is energized in a first phase, the first capacitor is discharged to produce an inverting voltage in a second phase, and the capacitor Cout1 is discharged to produce the inverting voltage and the second capacitor is charged to produce a boost voltage in a third phase. Therefore, the boost-inverting converter has lower peak inductor current and less power loss, and the limitation to the switch design for the boost-inverting converter is relaxed.
