Average value of the conducting phase voltages
What is the Difference between half wave and full wave rectifiers?
Half-wave rectification is achieved using a single diode in a one phase supply, or by using three diodes in a three phase supply. In half wave rectification, either the positive or negative half of the AC wave is passed and the other half is blocked. Since only one half of the input waveform reaches the output, it is very inefficient if used for power transfer. A full-wave rectifier converts the whole of the input waveform to one of constant polarity (positive or negative) at its output. Full-wave rectification converts both polarities of the input waveform to DC (direct current), and is more efficient.
Which phase of the Moon occurs when the Moon is three-quarters full just before the full Moon phase?
The phase of the Moon that occurs when it is three-quarters full just before the full Moon phase is the waxing gibbous phase. This phase occurs as the Moon is waxing, or growing larger, towards the full Moon.
Which phase of the moon occurs when the moon is three quarers full just before the full moon phase?
waxing gibbous
Which phase of the moon occurs when the moon is three quarters full just before the full moon phase?
waxing gibbous
Why three-phase rectifier is preferred upon single-phase rectifier?
The choice of single or three phase depends on the available supply. But a three-phase full wave rectifier provides 6 pulses of DC per cycle, while a single-phase full-wave rectifier provides only two. That makes the output DC easier to smooth.
A three phase load taking a full load of X Amps means it is sum of three phase?
In a three-phase system, the total load is the sum of the currents in each of the three phases. This is due to the balanced nature of three-phase systems, where the currents in each phase are equal in magnitude but shifted by 120 degrees. The full load of X Amps is the total current drawn by the load across all three phases.
Why use the capacitor in the full rectifier?
to smooth the output waveform

What is the simplest way to run a 3 phase 380 V motor of about 1 KW directly on 220 V single phase supply without resorting to rewinding or frequency converters?
You cannot run a three phase motor on single phase power. You'll burn the motor up within minutes. By the way, I've never seen or heard of a 380 volt motor. Do you mean a 480 volt motor? If so, the only way you can power it is with the correct full voltage and a 3 phase power supply.
Phase Converter Shopping Guide?
A phase converter is a rotating machine, quite similar to a motor. The machine converts single-phase utility power into 3-phase electricity for use by 3-phase equipment. We use a phase converter where 3-phase utility is unavailable, or when it is too expensive for us to install. A properly sized and purposefully chosen phase converter is an economical option that will operate any load as well as the utility 3-phase will, and a high-quality phase converter provides an ample lifespan. The primary decision the consumer must make is the choice between a rotary or a static phase converter. Rotary 3-phase converters are the most reliable type of converter, and they are the most flexible. They produce true 3-phase power, and thus they operated any type of load or combination of motors. Static 3-phase converters do not generate true 3-phase power, and are very similar to an electric rope starter. Once the motor is started, static converters cannot balance the load between the three legs. Therefore, using a static phase converter, the motor is never able to develop full horsepower. However, they are suitable for heaters, rectifier loads and single motor, small horsepower applications. The benefit of the static 3-phase converter is that it starts quickly, and it is substantially less expensive than a rotary phase converter. Therefore, if for your application, the motor can run at 70% of nameplate horsepower, and you start it infrequently, a static phase converter is a great choice. By infrequent, we mean less than four starts per hour. Customers must know that there are no industry standards that apply to phase converters. This means a couple of things for the consumer. One, the price between similar models can vary drastically. Two, low quality phase converters are far more trouble than they are worth. Make it a point to research phase converter brands, and pay the premium, if necessary, in order to get a high quality model of the type you require. In addition, never compare phase converters solely on the nameplate horsepower rating. Ask for the NEMA frame size, and then compare phase converters of equal frame size. Marketing often suggests that you can achieve similar/same output from a small frame size. This is impossible, so keep that in mind, and ignore the clever marketing.
