摘要： The invention provides a switching circuit and a power converter having a built-in power source for a conduction control terminal even if they have a single-arm structure. In the switching circuit having a switching device and a conduction control terminal power source capacitor, a negative terminal of the capacitor is connected to a reference voltage terminal of a main power source and to the gate terminal selectively through a half-bridge circuit and a positive terminal of the capacitor is selectively connected to a positive terminal of the main power source and to a source terminal of the switching device through a half-bridge circuit. The capacitor is charged when the positive terminal is connected to the main power source and discharges when the negative terminal is connected to the gate terminal and the positive terminal is connected to the source terminal and applies voltage to the gate terminal of the switching device.

The present invention is typically a circuit arrangement includes at least one switching device and a free-wheel diode connected in parallel with the switching device. The free-wheel diode is formed by connecting a silicon PiN diode in parallel with a Schottky barrier diode that uses a semiconductor material having a wider band gap than silicon as a base material.

摘要： A position-data converter and a motor-drive control device are connected. The position-data converter receives two-phase, sine-wave analog signals da and db from two first magnetic detectors, respectively, and converts these signals da and db to position data. On receiving a positioning instruction, the motor-drive control device calculates the value of current, from the current position signal generated by the position-data converter. The permanent magnets incorporated in a linear motor are used as components of a linear scale, as well.

摘要： In a conventional hybrid scheme used to mount a rechargeable battery in a motor vehicle, store into the battery the electric power that has been obtained via a regenerative brake, and utilize the power during acceleration of the vehicle, when a temperature rise of the battery due to charging or discharging causes a temperature of the battery to stay outside a defined range, it has been absolutely necessary to stop the battery charge or discharge, and fuel efficiency has decreased. This invention predicts a charge level and temperature of a rechargeable battery from the cruising input/output power requirements calculated from route information and historical records of cruising, prevents a stoppage of the battery by calculating chronological engine output and brake control data for the temperature to stay within a defined range, and hence improves fuel efficiency.
