Abstract
PURPOSE: To make small in size and low cost for the power unit in which output voltage is variable, by connecting the capacitor having capacitance of 10-3F or more in series with the switch in which the turn-on and turn-off time are respectively below 10-5 second, and obtaining the ON, OFF instruction signal of the switch from the output of the voltage comparator taking the output voltage and the set voltage as 2 inputs.
CONSTITUTION: Taking the voltage of the power supply 4 as V0, V, capacitance of the capacitor 1 as C Farad, equivalent internal resistor 5 as R ohms, the load of output terminal as r ohms, time of switch on as τ1 second ans switch off time as τ2 second, the variation V of the output voltage and the output voltage V(miximum value of voltage value in variation) are as shown in equations (I), (II). Thus, the voltage variation ΔV is almost inversely proportional to the capacitor C, then a large capacitance 10-3 or more is used.
