摘要： Conventionally, there is a problem that it is impossible to provide an analog signal detecting circuit having high reliability and long lifetime under a bad environment since a photocoupler is used for electrical insulation of a digital signal. Then, an analog signal detecting circuit is provided with a carrier wave generating unit for generating a carrier wave, a pulse width modulating unit for pulse width modulating an analog signal inputted from the signal input terminal by using the carrier wave generated by the carrier wave generating unit and for outputting a digital signal, a reverse level shift HVIC for transmitting the digital signal from one power supply system to the other power supply system, and a demodulation unit for demodulating the digital signal transmitted to the other power supply system into an analog signal and for outputting it to a signal output terminal. As a result, even in the case where reference potentials are different from each other at signal input/output terminals, an analog signal can be detected.

摘要： In the present invention, when a power module is soldered to a heatsink, steam which is temperature-adjusted to at least the melting point of a solder is introduced from a steam generating tank into the flow path provided in the heatsink, the heatsink is heated and the solder is melted. Inert gas is introduced into a soldering tank from another route so as not to mix with the steam supplied to the heatsink. Voids in the solder are reduced and condensed by pressure regulation and as a result the negative impact of voids is eliminated.

摘要： Three or more circuits, in which series-connected low-voltage and high-voltage side switches including MOSFETs including parasitic diodes are connected across positive and negative terminals of each of smoothing capacitors, are connected in series. One of elementary series circuits, each including a capacitor and an inductor, is disposed between any adjacent two of the circuits with the elementary series circuits set to have the same period of resonance. The MOSFETs of rectifier circuits are brought into an ON state simultaneously with the MOSFETs of a driving inverter circuit and brought into an OFF state earlier than the MOSFETs of the driving inverter circuit by a period of time not exceeding a time period equal to (period of resonance)/2. A resonance phenomenon of the capacitor and the inductor is used and conduction loss in the rectifier circuits is reduced in DC/DC power conversion performed through charging and discharging operation of the capacitor.
