Generator for Ripple Rejection Measurement of Voltage Regulators
Nekovář, Jiří ; Kubíček, Michal (referee) ; Šebesta, Jiří (advisor)
The aim of this bachelor’s thesis is the design of complete circuitry, mechanical solutions and build of generator, which will be use with osciloscope and millivoltmeter with pass-bands for measure the suppression of ripple voltage stabilizers. Circuit is power voltage generator with low output impedance. The individual chapters describe the generator including the integration of measuring instruments (DC voltage, effective AC voltage and frequency AC voltage). Functionality of the assembled generator was tested and subsequently the parameters was measured. Properties of frequency counter were improved replacing original circuit parts (gate circuit, reset and extension of range).
