To provide a heating apparatus and a method for producing a plate-like object that can heat a heating target object uniformly. The heating apparatus includes a heater 10 for heating target object W, and a support member 20 disposed on a front face 11f of the heater 10 and for supporting a face Wf of the heating target object W. The support member 20 supports the heating target object W in such a manner that: the support member 20 prevents direct heat transfer between the face Wf and the support member 20; a clearance between the front face 11f and the face Wf is maintained in a predetermined clearance S, wherein the predetermined clearance S allows a fluid to be present in the clearance but does not induce convection of the fluid. The method includes supporting the heating target object W with the support member 20, and heating the heating target object W with the heater 10 to produce the plate-like object.

摘要:
A static synchronous compensator that generates a second axis voltage command from the difference between the DC voltage converted by a single-phase voltage AC-DC conversion circuit and a set DC voltage command. When the voltage (the voltage of an AC terminal) of the single-phase AC power system increases, since the difference between the voltage of the AC terminal and an internal electromotive force increases, the static synchronous compensator carries out a PWM control to decreases the voltage of the AC terminal side of the single-phase voltage AC-DC conversion circuit. Since the voltage of the single-phase voltage AC-DC conversion circuit becomes lower than the voltage of the single-phase AC power system, an ineffective current flows from single-phase AC power system in the static synchronous compensator so that the voltage of the single-phase AC power system can be decreased.
