<p>This invention relates to improvements in a vertical deflection circuit employing a class D amplifier. The circuit comprises a pulse width modulator for converting a sawtooth waveform signal to a width modulated pulse train, a switch mode power amplifier for amplifying said width modulated pulse train, a demodulating filter circuit for demodulating said width modulated pulse train to the sawtooth waveform, a damping circuit for preventing a significant power loss in said demodulating filter circuit and a deflection yoke coupled to said demodulating filter circuit, thereby making it possible to reduce power dissipation in the circuit.</p> |
