    Abstract: A vehicle power distribution system includes a battery having a nominal voltage, a vehicle electrical load having a supply voltage different than the nominal voltage, and a monolithic solid state relay including integrated circuitry to convert the nominal voltage to the rated voltage and an output configured to selectively energize the vehicle electrical load with the rated voltage in response to a control signal from a vehicle controller applied to an input of the relay. The relay may include a PWM controller to provide a switching signal to a transistor connected to an output filter to step down the nominal voltage of the battery to the rated voltage of the vehicle electrical load. Relay output voltage and current monitoring circuitry may be connected to the PWM controller to provide over current and over voltage protection.

    Abstract: A motor drive device includes: an inverter circuit that has three switching elements corresponding to three phases of a three-phase motor coil, converts a DC applied voltage of a power source to an AC voltage by a PWM, and output the AC voltage to the motor coil; a voltage detection device for the DC applied voltage; and a control device that controls the PWM. The control device selects a first modulation method, for fixing the on/off-state of a part of the switching elements and for switching the on/off-state of the other part of the switching elements, or a second modulation method, for switching the on/off-state of the switching elements corresponding to three phases. The control device switches from the first modulation method to the second modulation method when the DC applied voltage is equal to or greater than a predetermined voltage, and the first modulation method is selected.

    Abstract: An object is to provide a semiconductor device that is capable of wireless communication, such as an RFID tag, which can transmit and receive individual information without checking remaining capacity of a battery or changing batteries due to deterioration with time in the battery for a drive power supply voltage, and maintain a favorable a transmission/reception state even when electric power of an electromagnetic wave from a reader/writer is not sufficient. The semiconductor device includes a signal processing circuit, a first antenna circuit connected to the signal processing circuit, an antenna circuit group, a rectifier circuit-group and a battery connected to the signal processing circuit. The first antenna circuit transmits and receives a signal for transmitting data stored in the signal processing circuit and drives a power supply circuit, and each antenna circuit of the antenna circuit group receives a signal for charging the battery and includes an antenna which has a different corresponding frequency.
