|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 - 50kV) and power levels (500J/sec to 30kJ/sec and above) 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. Capacitor charging supplies differ from conventional DC supplies in that the output current is fixed and not variable, allowing the load capacitor to be charged in the fastest possible time, with no requirement for series current limiting resistors. All of ALE's capacitor charging supplies have a fast inhibit input. This allows the user to start and stop load charging with a simple 0-10V input signal.
This feature is particularly useful in repetitive discharge circuits where inhibiting the supply output current after the load has been discharged aids in switch recovery. In addition to the fast inhibit control all of the standard power supplies feature a comprehensive control interface with programming and status signals.
The capacitor charging supply was originally designed to replace large command resonant charge supplies in high performance lasers. Even today the largest application for this type of supply is the laser industry. Although lasers are the largest users of capacitor charging power supplies, they also find applications in areas as diverse as medical sterilization and rock crushing.

Switchmode High Voltage DC
Alongside continuous DC versions of our ALE constant current capacitor charging supplies, we also offer precise and flexible HVDC supplies with fully programmable output voltage and current.
The PHV series offers a very broad range of power levels and voltages from 125V to 300,000V at power levels from 14Watts to 15kWatts. Standard models feature high precision, low ripple outputs, with 10-turn local voltage and current controls, with optional analog and digital interfaces. A large selection of available features include electronic polarity reversal, floating outputs, ultra low ripple and high stability. Visit the PHV page for more details.
The FLX-HV series offers multiple standard class leading features in a compact and cost effective design. Standard features include Active PFC with wide range 110/230VAC input, multi-function display with output voltage and current encoders, and standard integrated USB and LAN interfaces, all in a compact leightweight 2U high rackmount or desktop package. Visit the FLX-HV page for more details.
||Turn-key High Voltage DC Power Systems
from 1kV to 50kV, 60kWatts to 500kWatts
Multiple DC power modules can be operated in parallel to create very high power DC (or capacitor charging) power solutions to meet the extreme demands and applications.
Our Turn-key HV systems combine multiple 50kW building bloack with a standard master controller and filter/junction box to provide fully integrated and rack mounted power systems with outs voltage from 1kV to 50kV at power levels from 60kW to 500kW and higher. TDK-Lambda's high voltage turn-key power systems are the most versatile and powerful high voltage available, and are used to power radar systems, cyclotrons, TWTs, and Gytrotrons. Visit the HV systems page for more details.
