Switchmode Capacitor Charging Supplies

TDK-Lambda Americas' ALE Systems division is the oldest and most experienced designer and manufacturer of high voltage capacitor charging power supplies operating today. The wide range of output voltages (1 - 65kV) and power levels (500J/sec to 30kJ/sec) available from a single supplier is unique in the industry. ALE Capacitor charging power supplies are specifically designed to efficiently charge capacitive loads to high voltages with excellent pulse to pulse repeatability at very high repetition rates.

Switchmode High Voltage DC

Although the ALE series of power supplies have been designed to operate as constant current capacitor charging supplies, they can be used in continuous DC applications with the addition of an external filter capacitor. When used in DC applications the ALE series can often deliver more average power - see the product details for the actual rating.

Product selection

Due to the complexity of such products and their application in end-user equipment, ALE Systems has produced a series of application notes and an enquiry form to assist customers in the selection and use of the optimum solution for their requirement. These can be found at the bottom of this page.
