Types of Power Managers


Rectified Waves” by Omegetron is licensed under CC BY-SA 3.0

A rectifier converts AC power into DC power. The voltage of AC power alternates from positive to negative in cycles 60 times per second. Using a rectifier suppresses the negative portion of the AC voltage cycle, turning it into a pulsating DC current.


DC/DC Converter” by Charly Whisky is licensed under CC BY-SA 4.0

Converters are used for DC power only. The converter converts one DC voltage to another, which can be higher or lower. This is done by storing the input DC energy temporarily, then releasing that energy to the output at a different voltage.


Transformers” by Wtshymanski is licensed under CC BY-SA 4.0

Transformers are used for AC power only. They can either step down or step up the AC voltage in the circuit. For example, a typical household doorbell requires between 8 V and 24 V to operate. Since most household appliances require 120 V for operation, for the doorbell to properly operate a transformer is required to step down the voltage.

Explorer’s Log

  • The power requirements of your load and the power generation sources or power type (AC or DC) you have available to you dictate the type of power management device you need.
  • Selecting the proper inverter for any specific application is based on the appliance’s power consumption and the type of appliance to be powered.
  • Solar Stik offers a variety of power management components including:
    • Power Hub for DC power management
    • PRO-Verter for AC and DC power management
    • Power Pak for DC power management and energy storage in a single component
