摘要： An inverter device includes plural modules, each module being formed by a series circuit having a parallel circuit of a first switching device and a first diode, and a parallel circuit of a second switching device and a second diode, allowing a reduced size, high reliability, high frequency switching and low noise. Each module forms one arm portion of the inverter. Lifetimes of the diodes and the switching devices are set in a manner to equalize losses in the inverter. Preferably, insulated gate bipolar transistors (IGBTs) formed by diffusion are used as the switching devices since the lifetimes of these devices can easily be adjusted to optimize design of the inverter.

摘要： The voltage applied to a power converter is detected by a voltage detector, a function generator produces a voltage proportional to this detected voltage, and a high-pass filter detects an AC component superimposed on the voltage. An adder adds a bias voltage to this AC component, and an adder adds the output from the adder and the output from the function generator. The output from the adder is compared with a triangular wave produced from a rectangular wave generator, and a switching element is controlled to make switching operation according to the compared result. When a DC current is decreased by the AC component, a resistance current Ib is increased so that the AC components superimposed on the current and resistance current can be cancelled out.

摘要翻译： 施加到功率转换器的电压由电压检测器检测，功能发生器产生与该检测电压成比例的电压，高通滤波器检测叠加在电压上的AC分量。 加法器向该AC分量加上偏置电压，加法器将来自加法器的输出和来自函数发生器的输出相加。 将来自加法器的输出与由矩形波发生器产生的三角波进行比较，并且根据比较结果控制开关元件进行开关操作。 当通过AC分量减小DC电流时，电阻电流Ib增加，从而可以消除叠加在电流和电阻电流上的AC分量。
