Program uses for the numerical analysis full-wave or half-wave rectifier. Aside from this, was able will use for the calculation of any rectifier on sine generator of any frequency. Are written for DOS in turbo Pascal. Was able will run in DOS boxing. Advantage of usage of program is what besides the calculation of achieved voltage, calculates and dissipation on given resistors. Program uses already the 14 year for fast simulations of behaviors of rectifiers. Data show numerical without the graph.
Give you example of analysis of small rectifier. Program has been started with the command RCD / P i.e. for the full-wave calculation. Resistance R1 is substitute internal resistance of the small 4VA transformer from 9V. R1 calculates along the formula:
Rs i= resistance of secondaries
Rp i= resistance of primary coils
N=Up/US = figurative proportion transformer is measured freightless for 9V trafo N=22
Program demands the input of parameters. Last used parameters (are noted in rcd.dat in this folder) you offer on modification. input:
R1 i R2 in ohm, use 10E3 write for 10000
C in farads, allowed writes 2200E-6 for 2200uF
Umax is peek entry AC voltage (1.4 * Ueff)
Udiode is maximal drop voltage on rectifier
T is period of AC voltages in seconds (0.02 for 50Hz)
Koraka po periodu is number of points along period - typically 5000
Broj perioda number of periods before start analysis (has proposed automatically approximately the 20 Tao)
Program first perform calculation of achieved voltage on the condenser for the given number period, and then in the next period calculates dissipaton on resistors (in this period) also minimal, maximal and middle voltage on condenser.
Program makes possible and assigning the arbitrary number periods startings (from the zero so on more). Thus was able the started analysis anybody period who follow after start period. However, assigns period smaller from the recommended affect on the calculation also requires take that these data are worth only for this period, but not for steady state.
The upper calculation has shown that the small net rectifier with transformer 4VA (220 / 9VAC, Rp=1020R, Rs=3,6R, N=22, Umax=14Vp) in the full-wave connection with 50R load (180mA) loses middle voltage with 12.3V (at load 10MR) on less than 9V. The useful carried over power is only 1.6W!. Dissipate power in the transformer will be larger from P(R1) because of losses in the trafo tin and losses who because of current magnetizations overruns primary coil.
Program was able will use for the calculation of different rectifiers, signal detectors AC of signal (e.g. 220V nets) and for direct net rectifiers. Instead of R2 in the approximation takes that is R2=Usred / Isred. After the getting of middle voltage, recalculated R2 and all repeats. Was able will use and formulas R2=Usr * Usr / P. Here has been given P power which needs consume. Value R2 was able will change while does not get that obtained dissipation P(R2) equal strength which has needed absorb from rectifier. When has had complexes which wears out the fixed dissipation then convenient possibility of simulations of variation of alternating voltage (peak values of entry voltage) also then see himself how drop the voltage on the condenser in order to adjusts values R2 rewin the same dissipation on R2 (i.e. on substitute load).
Program is completely free. Was able freely will use and multiply. The every sale has been prohibited. Program is not influential on the operating system and does have not virus.
