Voltage supplying the load circuit Pulse input signal Current in the load circuit Fig. 14. Control of on-off type, runs of occurring signals (for resistive load). 6.2. Pulse control Pulse control consists on the change of the pulse-duty factor and the frequency of power Po delivered to the load in function of the analog control signal, at the same time the output current is turned on synchronously with the transition of the supply voltage across zero. - Page 18 T - period of the supply voltage, - number of turned periods on, - number of periods off. The RP1 power controller has following kinds of pulse control: Quick cycle, in which for X=1/2 (X = 10, however f = 2.5 Hz...
