A rectifier allows current to flow only in one direction. In a half-wave rectifier circuit, an input wave which oscillates between positive and negative, will 'pass through' the positive portion of the wave, and when the input is negative will output zero. A full-wave rectifier circuit, is commonly configured with 4 rectifier diodes, which allow a positive wave to output when the input wave is negative.

What is TPZi waveform?
A saw tooth wave form superimposed over a square wave form is TPZi wave form. Most of the Inverters use this technology instead of pure sine wave form of out put.
What happens to the load if reverse the polarity of diode?
if you reverse the diode in a half wave rectifier, you would expect the A- Ripple to increase B- output to be less filtered C- out put polarity to be reversed D- output voltage to decrease
Can you use transformer for DC supply?
No. Only Transformer could not be used for DC supply.If yoy need to have DC out put,then rectifier unit required .
How do you reduce a ripple voltage?
You reduce ripple voltage by adding a low-pass filter. In the simplest case, you put a capacitor after the rectifier. The peak voltage will be the rectifier output voltage less the forward bias of the rectifier, while the minimum voltage will depend on current and capacitance. In a more complex case, you could use an LC filter, making the peak voltage smaller. Specifics are dependent on the power and performance requirements.
What is the effect of capacitor in waveform of half wave rectifier?
is a device that smoothen your half-wave rectification into a full-wave rectification after using a 4 diode and 1 resistor , after adding a capacitor , there will be a almost steady output , it charges the capacitor when is forward biased which is the first half wave , and discharge when is reverse biased to stablelize the wave into a almost same potential difference compare to a.c
What is the form factor of a half wave rectifier?
It is defined as the ratio of RMS value of output voltage to the average value of the out put voltage.
What are the advantages and dis advantage of full-wave bridge rectifier compared with two diodes rectifier?
in full wave bridge rectifier, the input and out put voltages are same but in case of two diode rectifier the input and output voltages can be different as per requirement a there is a transformer in the circuit. The former is lighter and the later is heavier.
What is the relationship of the input frequency and output frequency in a FULL-wave rectifier?
The frequency of a full-wave rectifier is double that of the input, if the input is a sine wave or triangle wave. If the input is a square wave, the output is DC. If the input is a sawtooth wave, the output is a triangle wave of the same frequency.
What circuit is to be added to a full wave rectifier to produce a smooth DC?
put capacitor parallel on load (peak rectifier) or add low frequency pass filter (composed of L & C) to remove AC components
What is TPZi waveform?

How can you put 23 in simplest form?
That looks simple enough to me.
What is the Difference between half wave and full wave rectification?
Half-wave rectificationA half wave rectifier is a special case of a clipper. In half wave rectification, either the positive or negative half of the AC wave is passed easily, while the other half is blocked, depending on the polarity of the rectifier. Because only one half of the input waveform reaches the output, it is very inefficient if used for power transfer. Half-wave rectification can be achieved with a single diode in a one phase supply.In half wave rectification, either the positive or negative half of the AC wave is passed, while the other half is blocked. Because only one half of the input waveform reaches the output, it is very inefficient if used for power transfer. Half-wave rectification can be achieved with a single diode in a one phase supply, or with three diodes in a three-phase supply.in half wave rectifier only one diode is there. The diode will be forward biased in the positive half cycle and reverse biased in the negative half cycle. So the out put will be available only during the positive half cycle and the out put will be unidirectional.Full-wave rectificationA 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. However, in a circuit with a non-center tapped transformer, four diodes are required instead of the one needed for half-wave rectification. (See semiconductors, diode). Four rectifiers arranged this way are called a diode bridge or bridge rectifier: For single-phase AC, if the transformer is center-tapped, then two diodes back-to-back (i.e. anodes-to-anode or cathode-to-cathode) form a full-wave rectifier (in this case, the voltage is half of that for the non-tapped bridge circuit above, and the diagram voltages are not to scale).In a full wave rectifier during each half cycle one of the diode will be forward biased and output will be available across the load resistor. So we get continuous dc output throughout the cycle.no.. of diods 1 in half wave rect....
What happens to the load if reverse the polarity of diode?
if you reverse the diode in a half wave rectifier, you would expect the A- Ripple to increase B- output to be less filtered C- out put polarity to be reversed D- output voltage to decrease
What happen if all the diode in bridge rectifier is reversed?
it will work as a rectifier . because the AC current to be rectified will not be effected by this change. the out put DC polarity will be changed.
What tubes should you put in a mesa boogie dual rectifier?

Why am I getting only half the voltage out of transformer's secondary when tranny is wired in parallel with A and C wires attached to 1n4007 diodes going positive and center tap going to ground?
You don't have a full wave rectifier set-up. You need to use a full wave bridge set-up, and when you do, it'll put out 1.4 times the voltage of the secondary of the transformer.
