Key Points
• Power efficiency in motor control systems
depends on optimizing both motor efficiency
and inverter stage performance.
• Advanced modulation techniques, such as
five-state PWM, reduce switching losses by
keeping one motor phase constant.
• Low-power sleep modes, including hibernation,
minimize standby energy consumption by
shutting down nonessential functions.
• Qorvo enhances motor control efficiency with
solutions like five-state PWM, single-shunt
current sensing, low-power sleep modes,
smart gate drivers, and integrated power
management features.
