All of the explanations written in this document will be based on the schematics shown on Figure 1. As it is not intended to generate a deep and precise description of its performance, due to the complexity of the circuitry, this document will explain briefly the basic principles on which this circuitry is based.
  • Page 6 RECTIFIER, PFC AND FILTER. These blocks are used to obtain a corrected Power consumption Factor value (phi). This technique is used to reduce dramatically the harmonic contents of common domestic mains signals before it reaches the power supply itself. The PFC (Power Factor Corrector) reshapes its output mains waveform and produces a clear and smooth sine wave, in phase with the waveform delivered through the mains supply.

All of the explanations written in this document will be based on the schematics shown on Figure 1. As it is not intended to generate a deep and precise description of its performance, due to the complexity of the circuitry, this document will explain briefly the basic principles on which this circuitry is based.
  • Page 8 ANTI-ALIASING FILTER. The anti-aliasing filter, like on every digital equipment, is intended to allow signal processing of input signal bandwidths just up to a half the system’s sample rate < ∙SR ), to avoid A/D conversion errors. Our system has an input signal input bandwidth of 35KHz, so the anti-aliasing cut-off frequency is slightly above this value.
  • Page 9 OUTPUT FILTERS AND DC-PROTECTION. The output filters, together with the DC-Out protection circuitry, are made of this elements: A Differential mode filter. A Common mode filter. An EMI enhancement filter. A Zobel network-type compensating circuitry. The DC-Out protection circuitry. The Differential mode-configured filter is used to clean high-frequency voltage from the output signal.
  • Page 10 MUTE CIRCUITRY. The Mute circuitry modifies the feedback system in order to improve stability when the unit is turned on, this is, when the output modules suddenly receive the pulse trains, just after the amplifier’s warm-up cycle. The mute circuitry damps the feedback’s adding amplifier gain for a while, lasting a little bit more than the main unit’s standby cycle.
