In today's world, inverters play a vital role in various applications, such as home solar power system, inverter for office use, inverter for van, etc. Central to their operation is the concept of an inverter frequency, which determines the rate at which the current alternates direction.
The maximum inverter frequency depends on its design specifications, with most commercial models offering a maximum frequency between 10 kilohertz to megahertz.
If the distance and switching frequency are right, a standing wave forms. Voltage from the inverter pulse and the reflected wave add together increasing voltage to the motor. At long distances a 460V RMS output can exceed 2000 volts at the motor terminals.
To get higher modulation frequency, each pulse must be very short and the inverter output goes from 0 volts to 650 volts DC in one–millionth of a second. This can seriously stress the motor's insulation system. This is what the motor sees as the voltage pulse from a PWM output enters the motor windings.
