<P>PROBLEM TO BE SOLVED: To efficiently achieve high-speed and highly precise control by easily combining a power block with a control block which digitally controls the power block to mount on a circuit board. <P>SOLUTION: The power supply circuit is provided with: the power block mounted on a first circuit board and including a switching element; a second circuit board having more wiring layers than the first circuit board and on which a through-hole connected to a ground pattern is formed; a plurality of detection circuits for detecting voltages or currents in the power block; a digital signal processor mounted on the second circuit board and for generating a drive signal for the switching element; at least one connector for performing signal input and output between the first circuit board and the second circuit board; and a conductive guide pole for connecting the ground pattern formed on the first circuit board and the through-hole on the second circuit board. <P>COPYRIGHT: (C)2007,JPO&INPIT |
