Abstract:
1. A timing controlled converter circuit configured to supply a regulated output voltage to a load circuit, said converter circuit configured to switchably couple a time varying input signal to the load circuit for providing an output voltage having an average value equal to a pre-selected reference voltage, the converter circuit comprising: an integrator circuit configured to integrate the difference between the output voltage and the pre-selected reference voltage to thereby provide a control signal; and a switch configured to switchably couple the time varying input signal to the load circuit for controlled periods of time when the polarity of the output voltage and the polarity of the time varying input signal are the same, a controlled period of time commencing when the absolute value of the time varying signal exceeds the absolute value of the output voltage and terminating when the absolute value of the time varying input signal exceeds the absolute value of the control signal, to thereby maintain the average value of the output voltage equal to the pre-selected reference voltage.
