Module Contents#

soft4pes.utils.conversions.abc_2_alpha_beta(abc)[source]#

Convert a quantity from abc-frame to alpha-beta frame using the reduced Clarke transformation. The common-mode component is neglected.

Parameters:

abc (1 x 3 ndarray of floats) – Input quantity in abc-frame.

Returns:

Quantity in alpha-beta frame.

Return type:

1 x 2 ndarray of floats

soft4pes.utils.conversions.alpha_beta_2_abc(alpha_beta)[source]#

Convert a quantity from abc-frame to alpha-beta frame using the inverse reduced Clarke transformation. The common-mode component is neglected.

Parameters:

abc (1 x 3 ndarray of floats) – Input quantity in abc-frame.

Returns:

Quantity in alpha-beta frame.

Return type:

1 x 2 ndarray of floats

soft4pes.utils.conversions.alpha_beta_2_dq(alpha_beta, theta)[source]#

Convert a quantity from alpha-beta frame to dq-frame. The common-mode component is neglected.

Parameters:

Returns:

Quantity in dq-frame.

Return type:

1 x 2 ndarray of floats

soft4pes.utils.conversions.dq_2_alpha_beta(dq, theta)[source]#
