摘要： A switching circuit can reduce switching power loss and can vary at least one of the switching frequency and the conduction rate of switching of the switching circuit with less dependency on a frequency of a resonating circuit. A converter unit employs the switching circuit for expansion of control range of an output voltage. A primary switching element forming the switching circuit is provided with a resonance circuit and an auxiliary switching element. With the auxiliary switching element, resonance operation is achieved. The switching circuit is applicable to switching portions of a DC-DC converter unit, an inverter or the like.

摘要： A power source apparatus has a power factor improving circuit which uses switching elements (4) as buildup transistors. According to the power source apparatus of the present invention, a current carrying ratio of the switching elements is decided to be a value which is obtained by subtracting a number of proportional value of the power source current waveform from the maximum current carrying ratio. Since the device of the present invention does not necessitate a detecting circuit of the power source voltage waveform for outputting an instruction waveform, the circuit thereof is simple and is not affected by the voltage change of the power source and noise generated at the power source.

摘要： In a vacuum cleaner, both static pressure H.sub.data and a variation width .DELTA.H in the static pressure appearing when a suction port is operated are detected from a pressure sensor provided at a rear side of a filter within a main body of the vacuum cleaner; a current variation width .DELTA.pbi appearing when the suction port is operated is detected from a current of a nozzel motor for driving a rotary brush stored in a power brush suction port; an air quantity at the suction port is calculated from the current, rotational speed of a fan motor and static pressure; command values are newly obtained by performing a fuzzy calculation with the variation width .DELTA.pbi, static-pressure command value Hcmd; the variation width .DELTA.H and the static-pressure command value Qcmd; the variation width .DELTA.pbi and static-pressure command value Hcmd; and also the variation width .DELTA.H and static-pressure command value Qcmd as the input thereto; the rotational speeds of the fan motor and nozzel motor are controlled from the result of the command values; and further optimum air suction force is automatically obtained, depending upon the suction port under use and cleaning floor plane.

摘要： A converter includes a converter circuit 1 having a plurality of bridge-connected semiconductor switching devices for converting AC power into DC power, a smoothing condenser connected in parallel to the DC side of the converter circuit and a current detector provided in a condenser circuit to control a condenser current flowing through the smoothing condenser to be a set value. The condenser current is controlled to be the set value (e.g. zero) to thereby reduce the capacity of the smoothing condenser and make the converter small.
