摘要： PROBLEM TO BE SOLVED: To provide a power supply device, with which voltage reduction in an early stage at the time of detection of an overvoltage can be realized at low cost.SOLUTION: An amplifier circuit 110 includes a choke coil 172, a switching element 174, a capacitor 176, and a filter circuit 178. When no overvoltage abnormality is detected, a gate control part 140 drives the switching element 174 based on a pulse signal from a pulse generator 130. On the other hand, when a detection voltage of a voltage detection part 150 exceeds a warning voltage and an overvoltage abnormality is detected, the gate control part 140 controls the switching element 174 so that a drain voltage of the switching element 174 becomes higher than a voltage of a power controller 10 and lower than the warning voltage.

摘要： PROBLEM TO BE SOLVED: To provide a power conversion device that suppresses transitional biased magnetization of a transformer resulting from a voltage fluctuation without requiring any additional components.SOLUTION: A control circuit 13 decides a pulse width on the basis of a result of comparison of an output voltage of an output side circuit 12 with a voltage command, and controls switching of FETs 110-113 such that a pulse voltage having the decided pulse width is applied to a primary winding 100 alternately positively and negatively with time. Specifically, the switching of the FETs 110-113 is controlled such that the pulse width is updated every time the pulse voltage is applied three consecutive times. Biased magnetization of a transformer 10 can thus be suppressed even when an input voltage fluctuates. An existing capacitor for biased magnetization prevention is dispensed with. This can reliably suppress transitional biased magnetization of the transformer 10 without requiring any additional components.
摘要翻译：要解决的问题：提供一种功率转换装置，其抑制由电压波动产生的变压器的过渡偏置磁化，而不需要任何额外的部件。解决方案：控制电路13基于输出侧电路12的输出电压与电压指令的比较结果来确定脉冲宽度，并且控制FET 110-113的切换，使得具有将决定的脉冲宽度随时间交替地正负交替地施加到初级绕组100。具体地说，控制FET110-113的切换，使得每次连续三次施加脉冲电压时更新脉冲宽度。因此即使当输入电压波动时也可以抑制变压器10的偏置磁化。现有的用于偏置磁化防止的电容器被省去。这可以可靠地抑制变压器10的过渡偏置磁化，而不需要任何额外的部件。版权所有（C）2013，JPO＆INPIT
