A control device includes a target voltage outputter that outputs a target voltage that is a target value of output voltage of a power conversion circuit and an element controller that controls a switching element in accordance with the target voltage. Upon acquisition of an operation command that provides an instruction for startup of the power conversion circuit, the target voltage outputter raises the target voltage to a startup voltage that is below a rated voltage range of the power conversion circuit. In a case where at least one of the load devices has started up after acquisition of the operation command, the target voltage outputter raises the target voltage to an operating voltage that is greater than the startup voltage and is within the rated voltage range of the power conversion circuit.

Control device, power conversion device, and control method

A power supply device converts power supplied from a power source to power to be supplied to a load and supplies the converted power to the load from an output terminal. The power supply device includes a capacitor that includes a case, a first terminal exposed outside the case, and a second terminal exposed outside the case. The first terminal is fixed to a busbar. The busbar electrically connects the first terminal to the output terminal of the power supply device. The second terminal is fixed to an electrically conductive support that receives a reference potential.

An improved process for producing a formed activated coke for simultaneous desulfurization and denitrification, which includes passing a ground coal through a tubular or cylindrical carbonization retort by using a hot gas stream, to subject the coal to preliminary carbonization to obtain a semi-coke, adding a caking agent to the semi-coke and forming the mixture, subjecting the formed material to carbonization to obtain a formed coke, and transferring the formed coke from the top to the bottom of a vertical multi-tubular retort of indirect heating and cooling (cooling is optional) type that includes a distribution section, a heating section, an activation section and a cooling section (the distribution section and the cooling section are optional) arranged in this order (the distribution section is at the top), to activate the formed coke.
