A receiving section receives a supply request for product from a terminal set up at a shop or a terminal used by a client. A first determination processing section determines whether a product in stock can be reserved for an order. A first reserve processing section reserves the product in stock for the order when the first determination processing section determines that the product can be reserved. A second determination processing section determines whether a semifinished product necessary for manufacturing a final product can be reserved when the first determination processing section determines that the product reserve is inadequate. A second reserve processing section reserves the semifinished product for the order when the second determination processing section determines that the semifinished product can be reserved.

A pair of upper and lower semiconductor switching elements can switch between the conductive state and the non-conductive state when control voltages vary. A controller controls the levels of the control voltages to alternately turn on the upper and lower semiconductor switching elements. The controller controls the absolute value of the second control voltage of the lower semiconductor switching element so as to reach a mean voltage before and after the time of transition between the conductive state and the non-conductive state of the upper semiconductor switching element. The mean voltage is lower than the absolute value of a threshold voltage and higher than a reference voltage.
