At least one auxiliary unit (61) is engagable to and disengagable from a power takeoff (62) with the aid of manual and/or automatic switch means (63).

The output stage (A1, A2) provides inverting and non-inverting differential output signals on inverting (LON) and non-inverting (LOP) output nodes.

The manual command using wall-switch remains available, and memorized for the next opening.

An optional variable-speed reversing fan further minimizes the need for manual cleaning.

Two inverters are used, each having a non-inverting and an inverting input terminal and a non-inverted and an inverted output terminal.

Your owner's manual will have detailed instructions on using your transfer switch properly.

An inverter topology circuit, an inversion method and an inverter are provided.

An inverter circuit and a control method therefor, and an inverter circuit control device.

The first inverter and the second inverter are mounted on a common insulating substrate (210).

The capacitor is connected between an input of the first inverter and an input of the second inverter.

An input of the first inverter is coupled to an output of the second inverter at a first bistable node, and an input of the second inverter is coupled to an output of the first inverter at a second bistable node.

The circuit has a first inverter stage (n1, p1).

The SRAM cell includes a bistable loop of a first inverter and a second inverter.

The first inverter (30) and the second inverter (40) are disposed in a casing (2).

An inverter-integrated electric compressor (1) having a built-in inverter device (20).
