摘要： An inverter circuit (24) includes a bridge circuit consisting of a plurality of pairs of a high-side switching element (T1, T3, T5) and a low-side switching element (T2, T4, T6), a command signal processing section (50), a pulse generating section (56) for generating pulse signals to control the inverter bridge circuit according to the command signal to have a dead time to prevent short circuiting of the dc power source and a command signal compensation section (54). The compensation section (54) modifies the command signal according to a current voltage level of the dc power source to control the dead zone, thereby preventing deformation of ac output power of the bridge circuit.

摘要： A position detecting device (1) for a motor includes a resolver (10), amplifiers (111, 112) and a microcomputer (113). The microcomputer (113) corrects an amplified sine wave signal to have the same amplitude in both positive and negative polarities, and corrects an amplified cosine wave signal to have the same amplitude in both positive and negative polarities. The microcomputer (113) further corrects the corrected sine wave signal or the corrected cosine wave signal to have the same amplitude therebetween. The rotation position is determined accurately based on the sine wave signal and the cosine wave signal of the same amplitude, even if the amplifiers (111, 112) have different operation characteristics.

摘要翻译：一种用于电动机的位置检测装置（1）包括旋转变压器（10），放大器（111,112）和微型计算机（113）。微型计算机（113）将放大的正弦波信号校正为在正极性和负极性中具有相同的幅度，并且校正放大的余弦波信号以在正极性和负极性中具有相同的幅度。微型计算机（113）进一步校正校正后的正弦波信号或校正后的余弦波信号，使它们之间具有相同的幅度。即使放大器（111,112）具有不同的操作特性，也可以基于正弦波信号和相同振幅的余弦波信号来精确地确定旋转位置。
