a Heumann chopper is nothing but the Class D commutation of a thyristor.refer to the following link on class d commutationhttp://www.slideshare.net/prathikm/thyristor-commutation-techniques
Voltage
If the batteries have EXACTLY the same voltage, then nothing will happen, because there will be no voltage drop in the circuit, and hence no current. If the batteries have SLIGHTLY different voltages, then there will be a voltage drop in the circuit. Since there is low resistance, there might be high current, causing damage and/or an explosion. In all probability, however, there is enough internal resistance in the batteries to simply cause them to equalize in voltage.
Ohm's law is the basic answer. Voltage = Current * Resistance is ohms law. In order to find current divide voltage by Resistance V/R=I where I is current.
Linear
Jones chopper is known as voltage commutated chopper...it is one type of chopper..
A self commutated is one which the means of communication is included with in the inverter itself.This is the case for circuits including electronic poer switches with turn off capability.
In a chopper type amplifier the dc i/p voltage is converted into an ac voltage, amplified by an ac amplifier and then converted back into a dc voltage proportional to the original i/p signal
Choppers are dc - dc converters, on the basis of output voltage level step down chopper is used for output voltage less than input one. A buck converter is a step down chopper with a LC filter at the output end in order to reduce the voltage ripples.
A chopper transformer is a kind of transformer used in an switching power supply.The primary input voltage of it is a Direct current (D.C) unlike any other ordinary step down transformer which uses an Alternating Current (A.C).Chopper transformer uses a switching transistor to produce a secondary voltage..
chopper use a ststeing perpose..... dc means direct current that is low voltage
A chopper or DC-DC converter is a circuit or technique used to convert a constant DC signal into a variable DC signal where by using switching technique known as PWM(pulse width modulation). A chopper is a static device that converts dc input into dc output voltage directly. A chopper may be thought of as an ac transformer since they behave the same.
It is a chopper (a device for step up or down dc voltage from fixed dc source) for low or medium load.Its main advantage is that it only required one thyristor. Capacitor and saturable reactor make it possible.
An AC generator sending power to a rectifier which converts it to DC voltage.
