Abstract: Měnič je tvořen polovodičovou destičkou,
na níž je vytvořena minimálně jedna oblast
opačného typu vodivosti. Každá oblast je opatřena
minimálně jednou vodivou hlavní elektrodou,
která je vždy menší než tato příslušná
oblast s opačnou vodivostí a je připojena
k jednomu konci proměnného zdroje
napětí, jenž je polarizován v závěrném směru
přechodu polovodičová destička — oblast,
a který má druhý konec uzemněn. Mezi
vodivými hlavními elektrodami je vždy
umístěna další elektroda na izolační vrstvě.
Elektroda je připojena jednak přes první
diodu, polarizovanou v propustném směru,
se zdrojem napětí, který je dále uzemněn a
jednak přes opačně polarizovanou druhou
diodu, která je spojena s jedním koncem
kondenzátoru, jehož druhý konec je též uzemněn.
