Abstract:
A circuit for driving a plurality of capacitive actuators, the circuit having a low-voltage side, a high voltage side and a flyback transformer between the two. The low-voltage side comprises first and second pairs of low-side switches connected in series across an input voltage. The flyback transformer has a primary winding connected to the two pairs of switches. The high-voltage side has a pair of switches connected between the secondary winding of the flyback transformer and a ground and a plurality of capacitive loads and bidirectional switches to connect the loads to the secondary winding of the flyback transformer and a ground.
