Variable Pulse Width Circuit

US Patent:
4099072, Jul 4, 1978
Filed:
Feb 8, 1977
Appl. No.:
5/766651
Inventors:
J. Spencer Lee - Santa Barbara CA
Leon E. Stoddard - Goleta CA
Assignee:
Hughes Aircraft Company - Culver City CA
International Classification:
H03K 118
US Classification:
307265
Abstract:
A variable pulse width circuit comprising a semiconductor switch and a circuit of a pair of capacitors in series with the switch. The capacitors have a rectifier joining one side of said capacitors. The capacitors are in series with the load and are connected to a charging circuit. Two current paths are provided to enable charge of such capacitors under conditions where wide and narrow pulse widths of load current are obtained. Also obtained are higher and lower amplitudes of voltage pulses from the charging circuit.
