开关电源装置
摘要：
开关电源装置是在是否对线圈施加电压间进行切换的开关电源装置。开关电源装置包括：开关元件，包含互相共源共栅连接的常导通型的第1开关元件及常断开型的第2开关元件，所述开关元件在是否对线圈施加电压间进行切换；以及控制电路，检测开关元件的共源共栅连接点上的电压，且根据所检测出的电压来控制开关元件的接通。
摘要（英）：

A switching power supply device of the present invention switches an application of a voltage to a coil. The switching power supply device includes: a switching element that (i) has a normally-on type first switching element and a normally-off type second switching element which are cascode-connected to each other at and (ii) switches the application of the voltage to the coil,and a control circuit that (i) detects a voltage at a cascode connecting point and (ii) controls turning-on of the switching element in accordance with the detected voltage.
