Title: Rectifier circuit device
Inventor: YOSHIDA IZUMI
IPC: H02M7/12
Filed: 2019-04-05
Abstract: To solve the problem in which, by setting a measurement time of a chopping pause phase width based on a minimum rotation speed, a voltage command cannot follow a change in power supply harmonics caused by a change in driving condition, causing power supply harmonics to increase.SOLUTION: In a driving condition accompanying load fluctuations, a chopping pause phase width determined by a chopping phase width detector 212 in a third control unit 223 affecting an updated value of a voltage command is input to a variable LPF device, which is a low-pass filter with a cutoff frequency being a motor speed, which is an output signal of an inverter control unit. By adjusting a predetermined target DC voltage so that an output of the variable LPF device has a substantially predetermined phase width, a measurement time of the chopping pause phase width is no longer determined by the minimum rotation speed of a compressor, and the voltage command follows changes in power supply harmonics caused by changes in the environment so that power supply harmonics can be kept within regulation while reducing loss.SELECTED DRAWING: Figure 1

Filed: 2019-04-08
Abstract: To provide a stranded conductive cable 1A in the form of an eccentric coil winding cable 12 comprising a unit coil wire portion 7 and an offset coil wire portion 8.SOLUTION: A first center portion 7a of the unit coil wire portion 7 and a second center portion 8a of the offset coil wire portion 8 are arranged in a state of being displaced in opposite directions. Thus, unlike the arrangement in which the unit coil wire portion 7 and the offset coil wire portion 8 are concentrically arranged in a tight contact state, this arrangement ensures good heat dissipation of the eccentric coil winding cable 12, suppresses power loss by reducing the influence of the electromagnetic induction, and at the same time realizes the excellent flexibility and bending property of the eccentric coil winding cable 12.SELECTED DRAWING: Figure 3
