WebNov 5, 2024 · 1. Constant Frequency System. In this type of control scheme, the chopping frequency ‘f’ (or chopping period T) is kept constant whereas the T on (On-time) is varied. Varying T on means adjusting the pulse width, that is why this scheme is also called pulse width modulation. Some authors called it time-ratio control (TRC). 2. Variable ... WebThe chopping frequency f c is in the range of several kHz providing the DC voltage pulses which drive the load current. Typical wave forms are shown in Fig. 2. [4]. The upper trace is taken at the Drive output, the lower at the motor input. Each single pulse is characterised by some time parameters given in Fig. 3.
