Title: Control method for pwm inverter
Inventor: TAMURA YOSHIAKI
IPC: H02M7/48
Filed: 1995-03-01
Abstract: PURPOSE: To reduce noise caused by carrier frequency by shifting the phase of carrier signal of each phase by 1/(phase × f) per phase when the frequency of the carrier signal of inverter is f. CONSTITUTION: If a carrier frequency is f and the number of phases of a motor 3 is N, then carriers (C1 C2,... CN), which has the phases deviated each other by 1/(f.N) sec. will be generated by a carrier generator 10. The respective carriers (C1 , C2 , CN) are sent to current controllers (61 , 62 ,...6N) of the respective phases and then individual current is controlled. As a result, the output voltage pulses of each phase will have different phases, and the total output power of the inverter will have a waveform with less pulsation. Thus, by reducing the pulsation of the whole inverter output power, the energy exchanged between the capacitor and the inductance of the motor can be reduced and, as a result, noise based on the PWM control can be decreased.
