2. a) i. Represent the waveform of the voltage across the load $U(t)$, the diode $U_D(t)$, and the chopper $U_H(t)$.
When switch H is closed ($0 \le t \le T_{ON}$):
The supply voltage $U_S$ is applied across the motor (load). $U(t) = U_S$.
The diode D is reverse biased, so $U_D(t) = -U_S$.
The voltage across the closed switch H is $U_H(t) = 0$.
*When switch H is open ($T_{ON} < t \le T$):
