    摘要: To prevent malfunction or breakdown due to a surge voltage in a power converter for converting DC into AC or the like so as to supply electric power to a load, not only a control signal is transmitted via a level shift circuit which is provided correspondingly to each of switching semiconductor elements forming a main circuit and shifts a level of a reference potential at its output side so as to follow variations of a reference potential of the switching semiconductor element to the switching semiconductor element, but a DC control power source for supplying electric power to the level shift circuit and a negative pole of the switching semiconductor element are connected to each other through at least one of an inductor and a resistance.

    摘要: A display panel for displaying an image, a drive circuit for driving the display panel and a rear plate for supporting the display panel are provided. The drive circuit includes a circuit board fixed on the rear plate, semiconductor devices surface-mounted on the circuit board to be connected to a plurality of electrodes formed on the display panel and radiator plates attached to the other surfaces of the semiconductor devices opposite to the surfaces mounted on the circuit board so as to be almost in parallel with the rear plate.
