Abstract: A control circuit is driven by a driving voltage (VOC) generated by a generator circuit, and outputs a control signal. A drive circuit is driven by a driving voltage (VOD) generated by another generator circuit, and turns a switching element inside a switching circuit on or off by supplying, to the switching circuit, a drive signal based on the control signal. During activation of a switching device, a voltage generation controller detects a voltage value of the output voltage (VOC) of the generator circuit, and allows activation of the other generator circuit after verifying that the detected voltage value is at or above a designated threshold.

The controller has a control mode in which the inverter circuit is controlled such that an output voltage of the solar panel is maintained at a voltage higher than a maximum power point voltage. In this control mode, the controller performs the control such that a rotation speed of the motor is changed repeatedly at predetermined timings.

Abstract: A highly efficient and low-cost switching power supply device includes a high withstand voltage transistor and a low withstand voltage transistor. When current flows from a second node to a first node, the high withstand voltage transistor turns on and the low withstand voltage transistor turns off, causing current to flow through a built-in diode of the low withstand voltage transistor. Since current does not flow through the parasitic diode of the high withstand voltage transistor, the recovery current is reduced. Furthermore, since a first delay circuit including resistors and a diode is connected to the gate electrode of the high withstand voltage transistor, and a second delay circuit including resistors and a diode is connected to the gate electrode of the low withstand voltage transistor, precise adjustment of the switching speed during switching operation is possible, and losses are reduced.
