Voltage multiplier circuits

Adding a DC housekeeping supply adds cost and complexity, often a simpler and less expensive solution is to use a voltage multiplier circuit.

Programs to solve AC voltage multiplier circuit require"odeiv"... 

Design a circuit for calculating the average value of three input voltages multiplied by 1000. 

A HV-bias supply is usually built around a DC/DC converter. An oscillator, push-pull circuitry, a transformer and a regulation circuit are necessary on the primary side on the secondary side, the AC is rectified and filtered or a voltage multiplier may be used. 

The third test point is the DC output of the converter. In most Instruments, voltage mullplier circuits are used. If there is no DC output on the last stage of the multiplier. It is worthwhile to test the other stages, because often only the last diode falls. 

This section will discuss three examples from the field of Eleetrieal Engineering, (a) an AC voltage multiplier cireuit, (b) the transient response of a CMOS circuit and (c) the pulse response of a linear amplifier. Almost all eleetronic cireuits provide nonlinear differential equations as the basie aetive eircuit elements of bipolar or MOS transistors are nonlinear deviees. 

Apparent power is the total power of a circuit and is measured in VA or kVA (1,000 VA). It is obtained by multiplying voltage and current. 

Circuit (a) works as an inverter of the input voltage because 0=- for R =R. It also works as a multiplying (or dividing) circuit, if the values of R and Rf are selected appropriately.
