This application note presents the concept of the continuous conduction current mode boost PFC with
nominal output power of 180W. The PFC is digitally controlled by a hybrid controller.
The Motorola 56F800/E families are ideal for digital motor control, combining the DSP’s calculation
capability with the MCU’s controller features on a single chip. These controllers offer a wide variety
of dedicated peripherals, such as Pulse Width Modulation (PWM) modules, Analog-to-Digital
Converter (ADC), timers, communication peripherals (SCI, SPI, CAN), on-board Flash and RAM. .
A typical member of the 56F800 family, the 56F805, provides the following peripheral blocks:
The Pulse Width Modulation (PWM) block offers great freedom in its configuration, enabling efficient
control of the AC induction motor.
The PWM block has the following features:
