    摘要: A motor driving apparatus makes a carrier signal of an inverter be synchronized with a carrier signal of a DC/DC converter, and determines a phase difference between both the carrier signals based on a ratio of an input voltage inputted to the DC/DC converter and an input voltage inputted to the inverter, and a percentage of modulation and a power factor which are operation parameters of the inverter. When the frequency of the carrier signal of the DC/DC converter is set to be twice as high as that of the carrier signal of the inverter, an optimal phase difference is determined based on the ratio of the input voltage of the DC/DC converter and the input voltage of the inverter.

    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.
