Title: Dc reactor-containing type inverter
Inventor: NIIMURA TERUMI
IPC: H02M7/04
Filed: 1996-03-19
Abstract: PROBLEM TO BE SOLVED: To make it possible to reduce in size and cost by the improvement in the power factor of a power source and the decrease in the capacity of a smoothing capacitor by incorporating a diode rectifier, a DC reactor, and smoothing capacitor and inverter connected to them in an inverter. SOLUTION: The DC reactor-containing type inverter comprises a diode rectifier 1 having three-phase input terminals, and a smoothing capacitor 3 supplied with the rectified output of the rectifier 1 via a DC reactor 2 and a series circuit of a rush current suppressing resistor 5 and a suppressing resistor short-circuiting contactor 6. An inverter 4 connected to the capacitor 3 and its output terminal are all contained in the inverter 10. Thus, the power factor of the power source is improved, and hence the output current of the rectifier is reduced to decrease the ripple current of the capacitor. As a result, the capacity of the capacitor can be reduced in response to the contained DC reactor to realize the reductions in size and cost.
