First Claim
Patent Images
1. An active damping switching system, comprising:
- an active damping switching apparatus, including;
a damping capacitor;
a damping resistor coupled to the damping capacitor;
an input switch coupled to the damping capacitor;
a zero cross detector coupled to the input switch and configured to switch the input switch on and off responsive to an input filter current, and to split the current from the input filter in response to transient inputs to the damping capacitor;
a direct current (DC) power source coupled to the active damping switching apparatus;
a constant power load; and
an input filter disposed between the constant power load and the active damping switching apparatus.
