A PWM signal is sent to a permanent magnet DC motor through an H-bridge circuit. The PWM frequency is 100 kHz, the DC voltage source is 16 volts, and the specification of the motor is given as: voltage = 16 volts, no load speed = 1500 RPM, holding torque = 2 Nm. a. Draw the voltage signal delivered to the motor when the duty cycle is 20% and 80% (at least draw for 5 periods). Calculate the speed of DC motor when the duty cycle is 20% and 80%. Estimate the output power when the duty cycle is 20% and 80%. Assume that the motor efficiency is 100%. b. C.
