Hi, I am Tony Input Choke & Resonant Choke Power Supplies for RF
Linear Amplifiers Tony IØJX & Pesa IKØHIT) This page discusses
the Input Choke Power Supply (ICPS) and the Resonant Choke Power
Supply (RCPS), two approaches very well suited to realizing the
high-voltage power supply of an RF linear amplifier, them
permitting to obtain a very stable output voltage in presence of
a varying load (e.g. with SSB or CW operations). In all cases,
use of a full-wave bridge-type rectifier is here assumed. The
most common type of power supply features a very simple filter,
consisting of a plain capacitor (C) directly connected at the
diodes bridge output, with a resistor (R) in parallel usually
called the bleeder. Let us here call this circuit, shown in Fig.
1, the Conventional Power Supply (CPS). Fig. 1 The Conventional
Power Supply There are however other approaches offering better
regulation performance (i.e. output voltage stability) at the
expense of higher complexity and cost; in particular the Input
